More inter-company slinging of the mud lately, as Microsoft and Sony essentially devolve the games industry into a slightly less spectacular episode of The Jerry Springer Show.
Responding to comments from the inimitable Peter Moore that Microsoft is interested in possibly pursuing an initiative similar to Sony's Folding@Home scheme, Tretton questioned the Xbox 360's ability to undertake such a task, and went on to say that he'd be "very disappointed" if Microsoft are just looking for PR.
"I think to look at it as a marketing platform is something that a company certainly wouldn't want to do. I'm certainly not insinuating that's Microsoft's motivation, but I'm not even sure how relevant it is to what we're doing. Would they be even having this conversation if we weren't doing it? I don't know."
So of course this is hypothetical disappointment in a situation that is certainly not being implied. He'd never dream of claiming that he thinks Microsoft are a bunch of parasitic ambulance chasers who'd leech credit for helping medical science in a fashion similar to Sony.
"It's really ugly territory to get into, but let's take fighting a disease and see if we can get some credit for that ... It's not a cool game to play one way or the other so I don't want to even give the impression that that's our motivation, and I'd be very disappointed if they're looking for PR value or to try to suck off some of the goodwill that we're doing."
