Update: This all seems to be a matter of crossed wires. So far DX3 has only been announced for PC, but there's no confirmation of exclusivity.
Rumours are circulating that Eidos's Deus Ex 3 is to be a PC exclusive. This originates from a story on Bit-Tech today in which they (no longer - Ed) comment,
"It has been confirmed that the game is a cyberpunk prequel to the first game though and that it won't be getting a console release due to the complexity of the game."
However, they don't state where this was confirmed, and the peeps on the Eidos forums seem equally surprised. "Only the PC version has been announced so far," notes 'René', one Eidos Montreal's community types, continuing, "The magazine coverage we had last year were all PC... I dunno where that website is getting its info from!" (Thanks to Phill for the nudge.)
