From what I've seen, Hasbro isn't overdoing the TPM merchandise though... we might see more new stuff with Toy Fair, but I am not expecting to see much more TPM stuff.
Vintage - We get a wave of TPM figures in the TVC line... okay, nothing wrong with that. We are way overdue for new TPM figures, and they've been selling like crazy at Wal-Mart, the TRU stores that put them out are selling fast with their Buy 2 Get 1 Sale, and I assume they'll do okay at Target. And if anything, this is a much stronger "Wave 1" than the ESB wave that launched the new vintage line - we get a lot more "new" stuff in this initial wave.
Movie Heroes - This is going to suffer from the bad quality of figures... the first wave only has three "TPM Specific" figures... but again, the quality of most of the figures is the problem. Wave 2 looks a bit better, and does focus on TPM, but there's some "new" stuff here so I don't think it's that big of a disaster - however those should have been in Wave 1.
Clone Wars - Well, this is Clone Wars. Doesn't look like this is a focus for Hasbro this year, at least not in terms of making "new" figures, looks like they think they need to focus that on vintage, which in the long run is probably a smart decision.
The weakest link, I think is the Wave 1 vehicles... those podracers could spell bad news for that line... the Wave 1 deluxes are an absolute joke too... what's new about them? Nothing. And I think the MTT is a great idea, and better than Maul's ship because Maul's ship never does anything in TPM except land in the desert. It's a cool design, but at least the MTT saw action in the film, and has cross over appeal for the rest of the prequels and the Clone Wars - plus some people will army build it for dioramas. I can't see that happening with a $100 Sith Infiltrator, which would probably be better served as a $50-$60 toy.
Anyways, I think any downfalls we see with Star Wars from what we've seen revealed so far has more to do with repacking older figures at higher prices than special attention being given to TPM... the devotion to that film actually isn't overwhelming.
