Like others have said, the fact that there doesn't seem to be much outside of the Vintage line next year may help me some too. Not a lot of other stuff to buy (at least SW-wise). I was looking through Hasbro's NYCC slideshow, and looking at the upcoming waves, I could cut things back a bit if I wanted/needed to. Beyond the TPM wave, we're looking at this:
Wave 2 - ROTJ Deleted Scenes Figures
Wave 3 - Hoth Luke, Imperial Navy Commander, CW Anakin, Darth Malgus, Darth Vader
Wave 4 - Secura, Nom Anor, 501st Clone, Evazan, Kithaba, Wedge
Wave 5 - Re-release of the Bespin Han wave + Gamorrean Guard
Now, out of those, I'd definitely pick up all of the OT figures (aside from the re-release wave, I think I have enough of those - except maybe Gam. Guard). I'd also grab the CW Anakin, but I think if I had to pass on the other PT figures included there, I could. Secura might be nice, but I really don't care much about the EU ones and have lost interest in clones for the most part at this point. The new 501st might be better, but I was happy enough with the last version I guess. So, not counting extras, I'd be looking at 11 figures through those four waves. Not too bad. I'd get extras of some for sure, but depending how many more waves we'll have for the rest of 2012, it could be a lighter year overall on the SW side. The only other thing would be vehicles, if we see anything new/spiffy there.
An interesting point about the "buy in" price for new collectors and/or parents and kids. It does get more and more steep for people to get into the line, and for kids, I think they'd sooner have the Ultimate FX Sabers (we got these for our daughter and nephews, and they really are spiffy for a kids toy). Although we've gotten away from Legends this year, I still think that Hasbro has built up a pretty good library of "ultimate" versions of the main characters and army builders that they could either re-release or put in two-packs or something to help those people who are new to collecting (or parents buying for kids). I could always envision 2 packs of VOTC Han and EB Chewie, or the droids, or Obi-Wan/Vader or Obi-Wan/Anakin, or you could extend it to the current BP form of 3-4 figures as well. Anyways, it will be interesting to see where the line is headed. The success/failure of TPM 3D (the movie and the Movie Heroes line) could have a decent effect on where things head from here.
