Hey i'm new to the forums,
Ok, the way i see all of this, is that Sony have already bought themselves a bunch of loyal customers for the future. This is purely because of the hype that is being raised over the ps3, and talks of games releasing and this awsome new Cell. I think its great and i will show my loyalty to Sony, as i am sure many others will. I can only see previous X Box owners going and buying the 360 before Christmas, i can't think of any reason why a ps2 owner should just give up on waiting for something potentially much better and more powerful than the 360 just to go and buy one.
By releasing the 360 first, Sony can also see possible mistakes Microsoft have made by the way the public reacts to this console and use this to their advantage. Microsoft also run the risk of flopping badly then the word of mouth spreading sharpley reducing their sales, thus the ps3 and Sony dominating again. So to those unsure on which to buy or which will succeed. I put it to you that good things will happen to those who wait, and Sony i'm sure will find this out when they release the best console to hit the fan
As the revolution goes, if Sony release before them, then because of their reputation and all the hype everyone will spend all their saved piggy banks on the ps3 after all they have waited half a year, and to be honest i think there will be a lack of support after people have realised how good the Plastation 3 is, and therefore, some of the public could give up on them.
