My son still loves watching Playhouse Disney they have pretty much removed Little Einsteins from the rotation and replaced it with Chuggington; Special Agen Oso and Jungle Junction are on more often these days in place of Tigger and Pooh. "Tasty Time with Ze Fronk" has taken the place of "Feeling Good with Jojo" as far as the in-between shorts.
Also I don't think Chuggington is anything like Thomas, the Thomas shorts are nothing more than stop motion animation with an overlay of George Carlin reading a story from a book in a dry/monotone voice. I can't stand the Thomas shorts, Chuggington is a lot more bearable.
My son has taken to the new Chuggington, Jungle Junction and Oso shows rather well, I doubt he would be at all disappointed if they were to have a breakfast with Oso, Jungle Junction, Handy Manny, or any other of the Playhouse Disney lineup. But he prefers Mickey and the gang over any other characters, which is why I setup a character breakfast with them over the Playhouse Disney gang.
