I would be happy with a new 2D game for any platform as long as it's high quality. Jungle Run was not perfect but I preferred it over Fiesta Run.
Like it's said here, a new 2D game wouldn't sell that well on consoles but if it did, I would be more than happy to have a proper closure for the Ubiart games, making them a trilogy.
Focusing on mobile is a smart move. It's quite obvious that this is a kids game, just look at the Incrediballs, and that's fine - kids will probably enjoy it. It's not meant to satisfy the teenage/adult fanbase.
I think the cruel fact is that there isn't a creative force on Ubisoft wanting a new 3D game, pushing it forward and without that, I doubt the executives would put resources to the console development.
