Ubi aren't making games for PS3 or 360 anymore, unless you count Just Dance. The info came out of last night's financial info which also saw The Division delayed to 2016.
This is the current line up they have planned for the future, taken from a slide in the company's presentation:
As you can see next year is all about Rainbow Six Siege, Assassin's Creed Syndicate and The Division on console, plus one other as yet unannounced "triple A" game. Ubisoft boss Yves Guillemot has stated that for those four games there will be no last-gen version, saying that "all our titles, except Just Dance, will be new-gen and PC only". Just Dance probably gets a pass because the same presentation reveals that it was one of the top selling new IPs of the last 10 years. It's also a much more casual game, meaning most of the people playing it will likely be casual gamers and not set to update systems with any great urgency.
