Well, it's definitely not too soon since the PS3 is out in the US. Ideally it's good to have a site already established prior to the 'boom' of the console so that when search engines, etc pick up new users they will be able to find us and so on.
As for the PS3 info and name change, PS3News.com is it actually. Until PS4 in 7-10 years... then it will be PS4News.com HEHE. We will still cover other consoles as we always have (sponsors often want us to plug non-PS3 products, etc so we always try to accomodate them) but as you said, in coming months our primary focus will likely be in PS3 stuff. Thanks for the feedback too- Thumbs Up for you!
