I'm with others, I think Dan is hitting on something that a lot of us have given some thought to lately. I know it has been discussed before in the forums in various ways, but I think a lot of us are either running out of room, moving on to other things, or just content with what we have. I know that I personally am enjoying the quality of stuff we're getting probably more than ever, and I'm pretty psyched about the upcoming Vintage Collection as well and all its nostalgic goodness - but at the same time I'm constantly assessing what I want/need in my collection, as it has just become so much to keep track of and display/store these days.
I'm someone who doesn't necessarily want to collect stuff to just put in storage, I'd rather display as much as I can (when possible). I'm restricted to one room (our office) in our house, and between Star Wars and some "other" lines (primarily Marvel/DC), it is getting to be pretty full. I still enjoy it all, and don't really "regret" anything I purchase these days - but I don't necessarily need our office/collection room to look like a Toys R Us or a kids playroom. I've thought about cutting out anything prequels/CW outside of the figures, but then things like the AT-TE (for $50) and neat ships like the V-19, CW starfighters, etc. come along. I try to swear off "other" lines, then things like Indy, 25th Joes, Marvel Legends/Universe, and DCU and MOTU Classics come along. That, along with trying to display not only Hasbro 3 3/4" stuff, along with things ranging from glasses to 7" Unleashed to Galactic Heroes makes it a bit crowded. I have to say, along with budgetary concerns, the main reason I'm constantly trying to figure out what to collect is the simple fact that I don't have that much room anymore. I really like a lot of the stuff coming out these days (not just SW, but toy lines in general have improved so much over the past few years I think)...but it is just hard to buy when there is nowhere for it to go.
