Yeah, it is tough for me to know what I want for the future of the VOTC/VTSC line. Although they are probably my favorite overall "line" of figures in the modern era - with, for the most part, exceptions sculpts/articulation and the nifty vintage cardbacks - at the same time I echo the thoughts here of the prices being high enough already. Plus, we pretty much get "VOTC quality" in the basic line at this point anyways. Heck, the Obi-Wan from the latest TLC wave (which I think was slated for the Evolutions line), is a near perfect figure, and much better than the previous VOTC version.
If they made more (at least in the same format), I'd buy them - but I'd be ok with what the collection is at this point too. Like others have said, we'd likely be looking at $13 figures (or more) with today's prices, and it is tough enough paying $8 for the basic line. I'm just a sucker for the vintage cardbacks and look. I'm not a carded collector, but that is one line that I picked up an extra carded set for just because they look nice all together I think.
It seems like Hasbro has mentioned in the past that if/when this line comes back it will likely contain all the movies, and will probably be a little bit different than what we are used to. I think it has been discussed before, but the OT probably has enough "big guns" that haven't been hit yet (Hoth Luke, Bespin Han, etc.) that they could realistically get another one or two waves out of this concept and still have hopes of selling them at the higher prices. Overall though, like I said I'd definitely pick them up - but if it ends with the group we have, that is ok too. I always thought they would be a good format if/when the line starts drying up (which doesn't seem real likely now with the TV opportunities), and they went much more limited or online only. I could picture something like the MOTU Classics line (except hopefully not as highly priced) where you could buy 3-4 VOTC styled figure each month from HTS. It probably wouldn't be ideal for everyone, but I could see that sort of avenue for "premium" figures - which is what VOTC was originally supposed to be. The same can be said for Evolutions, which sounds like it will also be "on hiatus" after this year. I will say that Hasbro has really stepped up on the recent basic figures (at least for the most part) to the point where many of the figures are "vintage" quality now anyways.
