I'm guessing they don't do it because it costs too much to implement. It effectively means they need to produce twice as many GPUs for a single console. The other side is that some PC games don't have that much improvement when running SLI or X-Fire depending on the amount of effort the devs have put into the feature. Crytek push anything that gives a graphical edge, other devs don't bother. The improvement is down to the game and giving the devs extra work can be detrimental in getting games on your system as Sony have discovered earlier in the gen.
