There are all kinds of rumors being tossed around the internet concerning the capabilities of the next generations consoles. So far it's just rumor and speculation as there have been no official announcements. Sony CEO, Kaz Hirai, says that Microsoft can open up first.
We don't know exactly when the next generation consoles will hit the market, but in an interview reported by The Times, Mr. Hirai was quoted as stating, "Why go first when your competitors can look at your specifications and come up with something better?"
This sounds more like an off-the-cuff comment than anything of real merit. Given that the PlayStation 3's release a year after the Xbox 360 did nothing to help Sony, and the fact that if the console is already under development, with developer kits distributed to 3rd parties, it would be almost impossible to make any major changes to the design in a short notice time frame.
There is a good article on GamesIndustry about the next generation PlayStation console, but until the hardware is in the hands of people playing games we won't know how well they perform, how reliable they are or how they compare to any other gaming hardware.
What do you think? Just a lot of bravado or a cunning plan?
