This is a wonderful article I found on insomnia.ac about why the Xbox 360 and PS3 are just not powerful enough and how both Microsoft and Sony have gone down the wrong path... the Marketing path. I would easily compare this to the AMD/Intel/Apple (RISK CPU) days when everyone was in the pissing game of who has the fastest (Mhz rating) CPU because that somehow "automatically" gave them a lead. That is until Intel hit the 3Ghz barrier and then the game changed.
I think Alex Kierkegaard (who wrote the Xbox 360/ PS3 article) has made some excellent points. He IS in fact talking about what few know... and even fewer are able to discuss. It's such a political game now with the game companies that no one can really say what they think afraid of insulting them and hurting any sort of relationship they might have with them. More recently articles have popped up saying that the Xbox 360 is much easier to program for then the PS3... and if you read those its clear how much everyone is holding back, being so very very careful as to what they say. It's sad really...
So I'm very happy that people like Alex are out there, and I hope they continue to spread the truth. I don't mind that Microsoft and Sony have chosen this path (it is their decision to make after all) but notice how much better Nintendo is doing going down a completely different road... interesting isn't it... maybe resolution isn't the goal the big boys should be going after, even if Marketing tells them to. I do hope the next console generation will focus almost entirely on graphic detail since the resolutions will be the same (HD). I guess time will tell.
