For me, it's not much. I'm not the wealthiest fellow, and my life's financial complexities have increased since my personal life's gotten more involved, so toys I have weeded out over the years...
For instance I've cut the 12" line out completely though I'd LOVE to be picking up the SideShow SW line and LOTR lines.
LOTR I cut off and should probably sell what I have that my brother doesn't want.
Starcom, a little line from the 80's I used to love, I've omitted totally, and should sell what I have there as well. I keep thinking I'd get back into it, but I don't.
I've got my SW basic habit down to just the 3.75" figures. I don't buy all ultra/deluxe ($10 pricepoint) items anymore... Just what I really dig. This saved me $20 just for the Palpatine and Obi-Wan figures for ROTS, haha.
If Hasbro does go with Chase Figures for the basic line, I'm going to be cutting down to just what I like as well. I refuse to pay above retail (unless it's shipping) on anything. I haven't since the line began, I won't start now. I'd feel defeated by the big H then.
Army building's a big part of my 3.75" habit so I'll be certain to do that this year if I can...
Customizing's my other habit... I've been slacking all last year, likely will this year some too.
Other lines I'm going to be buying though:
-21st Century Toys and more particular, their XD 1:18 military line. I've cut out ships/choppers on this line though, and I'll be sticking to figures, and land based vehicles (tanks, armor, artillery, playsets, and figures with army building a focus). 21st's harder to find than Star Wars though so yeah, another headache.
-BBI's Elite Force... I missed on their tank, and I haven't seen the latest WW2 figures, but I buy the modern as I see them, have the WW2 Jump Paratroopers... I'm going to be cutting out modern vehicles all together though, no doubt, and sticking to just modern figures. WW2 will be my vehicle focus. I mean, 1:18 tanks take up a lotta space as you get many of them.
-Other random 1:18 military things... I'd be happy to get other things to complement the last two lines I'm collecting. That's more a "see it and buy it" thing though. I know of no other planned 1:18 military lines.
And that's it.
My girlfriend has kids, and they've been into SW this past year, so that's cut into what I can spend on me... I try to keep them up with some of the figures they really want. Right now, finding 3 Boba Fett's for her kids and their friend is a bitch.
That's it for me though...
I'd love to have gotten some GI Joes, but I'm maintaining my composure and not jumping on that line.
I got an RC tank on clearance (1:18 XD tank) and holy **** this thing is fun. I can't give up this line, it's too friggin' great. It's all quality the SW line needs to keep up with.
