I'll probably pick up one of the newer 40s now rather than a used 20; I won't be getting rid of my slim Ps2 so I could (honestly) care less about b/c.
Next year will be a much better year for Sony. I'm not saying they're entirely in the crapper but the first year is always cruel no matter what console we're talking about. 360 was largely forgettable the first year which is why I didn't buy one 'til the GoW launch (the first must own for me on the system). Wii first year thus far has not impressed me much but I'm not counting them out; similarly for the same reasons I'm not counting Sony out either.
It's a little too early for some people to be burying these systems but to each his own...many excellent gameplay opportunities will be missed as always
