For me, my basic "standard" is ball/socket knees, angle-cut elbows, ball/socket neck, and I'd like ball/socket shoulders. THat's what I think should be standard for the line, however an army builder like the DST should get a little better... SA or damn close to it (IE: I could lose the ankle joints and ball/socket torso, but that's it).
That idea with multiple heads is a good one too Paul considering 21st Cent. Toys is getting in the habit now of including an ENTIRE torso with some upcoming figures for "army building" variety it seems, plus multiple heads with some figures. Hasbro can do the same or better I'm sure, especially since their figures sell for $1 or $2 more each.
I've got some renewed hope with the Clones and Firefighter recently pictured but when I look at Veers I just think how bad Hasbro could tank a resculpt of the Death Star Trooper...

That Veers figure just lacks quite a bit in my book (Like a removable hat, the back of his armor, and knee articulation).
