this is nothing earth-shattering, anyone with any commen sense and a brain in the industry will tell you the same thing. that is the same reason why i never took bill gates comment on halo 3 launcjing the same day as the ps3 literally. in retrospect the same has been said about the 360 from sony execs. it was admitted before the launch of the 360 that if the launch wasnt a success then sony may opt. to wait until 2007 to launch, but was quick to also say that the 360 wont be a failure and they knew it.
this lesson should be learned by all from the dreamcast launch. sony released FFVIII the same day as the DC launch hoping to steal some of the attention away from the DC. peter moore even commented on how it would not make any difference because those who are going to buy a system at launch will get it regardless of what else is out. though a good try, FFVIII had no effect on the DC successful launch and those who wanted one or both got them regardless of anything else. basically moore saw how futile it was then with the DC and knows the same thing now with the ps3.
