I've bought too much stuff this year, but I think I'm pretty happy.  I'm sticking with Poser in the sense that I expect to use it for what it does well, and I'm looking forward to future versions in hopes that they will address my needs with regard to improvements.  If I actually had time to learn the programs I have well enough to use them together it'd work like this.

Hexagon: Low poly figures, vehicles and mechanical stuff.
zBrush: for sculpting and detailing Hex meshes into high res figures
Poser: for rigging figures, posing, animation, some rendering
Truespace 7.5: Photoreal renderer for quick, high quality animating
Carrara 6: High quality rendering, posing of figures, environments

Unfortunately, there are still alot of hurdles preventing these programs from working well together.  I can't get Poser figures into Truespace yet, and while both Carrara and TS will eventually export Collada, neither of them will import it.  Anyways, that's probably the last software I'll ever buy.  Aside from upgrading those programs, I can't imagine anything I'd ever need not being in there somewhere.  I would like to learn blender though for its fluid sim.
