Barnsley's promotion, together with Sheffield Wednesday's defeat at Wembley last month, means there are eight Yorkshire derbies for Huddersfield Town fans to look forward to in the Championship next season.
And with two unveiling new managers, it should be an intriguing season in this corner of England.
Garry Monk has been confirmed as Leeds United head coach, while Alan Stubbs has arrived at Rotherham to replace Neil Warnock.
We examine the state of play at each side, and you can have your say on who will be Yorkshire's top dog...
Huddersfield Town
David Wagner begins his first full year in the John Smith's Stadium hotseat, and pre-season will be a different beast this year.
The players report back on Friday June 24, and will head off for a "squad bonding" trip to Sweden, before a training camp in Austria later in the programme.
Plus a plum friendly with Liverpool has been confirmed alongside dates with Guiseley and Oldham Athletic.
Michael Hefele and Chris Löwe have already signed ahead of next term, while Rajiv van La Parra's loan has been made permanent. Luke Coddington will work with the u21s.
More are due to follow, with two goalkeepers still needed for the senior side, plus new forwards on the shopping list.
Town will have been disappointed to finish 19th last term, with relegation never a serious worry, and will have their sights set on an upward trajectory in Wagner's first full season in charge.
Barnsley
Newcomers to the Championship, Barnsley are still on a high after a 3-1 victory over Millwall at Wembley confirmed their return to English football's second tier.
And they have no intention of standing still.
Kayden Jackson, Stefan Payne and Andy Yiadom have all been confirmed as incomings as the club looks to strengthen the squad for the rigours of the division.
However, loan deals for Ashley Fletcher from Manchester United, Josh Brownhill from Preston North End, and Lloyd Isgrove from Southampton have expired, and other clubs are circling around Adam Hammill and Alfie Mawson.
Paul Hecklingbottom, who as caretaker guided the Tykes to victory in the Football League trophy and League One play-offs, is the favourite to be appointed permanent boss but as yet no announcement has been made.
Survival has to be the initial priority.

Leeds United
After months of speculation, Leeds have confirmed former Swansea City manager Garry Monk as the replacement for Steve Evans.
However, while owner Massimo Cellino remains in overall charge, Monk will have to carry out his duties against a background of fan protests - although it should be noted the manager is rarely the target.
Evans was given a good reception at his last game while fan group Time to Go Massimo have already tweeted their support for the new man.
That said, stability remains elusive at the Elland road club.
Supporters have been dreaming of a return to the Premier League for more than a decade - but SkyBet give longer odds on promotion (8/1) than on relegation (4/1), underlining the size of the challenge.
Mirco Antenucci and Scott Wootton have been released, and the arrival of a new man in the dugout should see an increase in transfer activity for the Whites.
A 13th-place finish last term was not enough to keep Evans in a job.
Rotherham United
A season which looked doomed in February concluded with the great escape, and Rotherham confirming their Championship status for another year under Neil Warnock.
Tempting the 67-year-old former Town boss out of retirement proved a masterstroke, but the club could not reach an agreement for him to extend his stay past the summer.
Instead, Alan Stubbs has been confirmed as the new man - arriving at the New York Stadium fresh from guiding Hibernian to their first Scottish Cup in 114 years.
The Millers have begun the process preparing for next season in advance of that official confirmation by revealing their list of retained players, and the release of 11 players, including Luciano Becchio.
Stubbs said that Rotherham "matched his ambition", and will hope to avoid putting Millers fans through the wringer with another relegation scare.
Sheffield Wednesday
The Owls came agonisingly close to the promised land of the Premier League, and its associated riches, losing to Hull City in the play-off final at Wembley last month.
Now Carlos Carvalhal must dust himself off and prepare his team to go again - only hoping for a different outcome in 2016/17.
Sheffield Wednesday finished 6th in the Championship last term, and saw off Brighton in the play-offs 3-1 on aggregate, but fell to a single strike from Mo Diame at English football's national stadium.
Wednesday are yet to announce their retained list, but Carvalhal has promised every effort to upgrade the squad while Kieren Westwood is attracting Premier League interest.
The Owls look well-placed to challenge for the play-offs once more, but the strength of the teams on the way down from the Premier League (and the associated parachute payments) makes the race for promotion an unpredictable battle.
