I don't see how you think TPCi can't
just click their fingers though. They managed to get their act together to get Black and White out on time, and while you're right in that it was mid-generation, they had no issues reducing the gap to the smallest it's ever been for B2W2, there were no issues with rushing or workload from what we can tell. They barely even have a gap to close now if they did want to do it. TPCi seem to have tons of control over the show, they took a show that was lagging behind and then managed to have everything running smoothly by the time BW launched and it's been running consistently alongside the franchise ever since.
So really, TPCi isn't the problem here at all. The only limitations are what's stopping TPCi, whether it's TV Tokyo, Cartoon Network, any other parties or the law/rights.
