UPDATE: Bethesda's Pete Hines has tweeted that this rumour is "complete bollocks." Good.
It's super unconfirmed rumour time, folks. Kotaku (as usual - but they're usually right) reports that Bethesda and Zenimax have decided to indefinitely postpone development of id Software's Doom IV after the incredibly messy PC launch of RAGE. Their source suggests the negative publicity about the PC release woes inspired "a serious lack of confidence in the project management at id." Naturally this whistleblower is both anonymous and unconfirmed, meaning that this could well be a load of old cobblers.
If true, though, the logic sounds a little bizarre to me (as a raving Carmack-fancying id fanboy, I grant you). RAGE charted well, and Doom IV won't use the Megatexture tech that got the PC version in such hot water. Plus, Doom is likely to sell better than RAGE thanks to its illustrious branding.
Then again, this is the company that sued Mojang over the use of the word "Scrolls." Anything is possible.
