I got it from Serebii:Radoh said:Could you back that up, by chance? Because from what I see it looks like this will go at least until Drake and the Champion fight, so it seems like it's willing to go the entire way there.FourCartridge said:Before the hype train sets off, it's only a special and not a full series. Ash will still be around for the time being. =(
Unless of course it goes the way of cutting out everything other than the important bits like Gym Battles, then that would make sense.

It states that Red is going to face Team Rocket at Pokemon Tower, but no mention of the Pokemon League except for Brock. It does say thet it's a special though, so I don't think there's something wrong with that.
