This is wierd news. Xbox one was e3 in retail form confirmed. Ryse, forza 5 and killer instinct all ran on real xbox one retail hw. Confirmed by digital foundry, ign and the devs of those games.
what's strange is i got the impression from some unamed sources for rumours that it was Microsoft behind on the launch
this would imply that Sony are the ones behind.
at games on there were over 40 xbox one retail hw there for titanfall, forza 5 et . Rows and rows of xbox ones at gamescom.
i remember Microsoft getting stick for some devs at e3 using pc devkits. It should have been aimed at Sony really. Both e3 and gamescom have gone by and still noone has seen or played actual ps4 hw. Hmmmm
is Sony this time the ones struggling with heat or yields?
Well a PC running different equipment (Nvidia graphics) was a pretty big thing compared to running dev kits.
According to the MS PR guy (there is a post somewhere around here for it).., the machines at gamescom were not retail, they were *nearly* retail... whatever that means.. but that would suggest they were devkits as well. The benefit MS has over Sony is that their devkits look the same as the non devkits to the untrained eye.
If you read my post further up, there is no real reason to *not* run dev kits at these shows. I'm not too concerned right now considering they have given a launch date and listed the countries which are more than MS. But it has been very difficult to predict who has been having problems, and Sony info has been pretty tight... but at the moment all things suggest Sony are not having Manufacturing issues/problems.
