Theres very little reason to care about how strong a console will be besides maybe a few key items like a network card or whatever or their storage medium as that will dictate the games that will be made or the attractiveness of the console itself. Get the games you like >_>

I would say give the consoles a year and a Christmas or two...then we can accurately judge which games you want. I made the mistake of buying a few consoles early and not knowing which is best in the end and you KNOW it will drop price eventually. If anything buying the current gen systems with most of the games out now, is the best money management ever.
