My thought is this: Games Workshop is currently being stupid and short-sighted. GW is in trouble. Warhammer 40k is not in trouble; the IP is too large, and too popular to be left to rot, and so I'm holding on to my armies until somebody (whether GW or an outsider) comes and fixes things, and in the meantime I'm willing to spend my hobby dollar on releases that look worthwhile.

There's also the slight caveat that at the rate I manage to get things painted, it's entirely possible that the rules side of things will be fixed before I actually have 2000 points of stuff that matches.
