TIMN reports that Google’s head of mobile, Andy Rubin, dropped a bombshell during his on-stage appearance at the Intel Developer Forum, by announcing that all future versions of Android will be optimized for Intel chips top to bottom. Intel also showed off a prototype Android tablet and phone running on the Medfield chip. Medfield is Intel’s fourth-generation mobile Internet device platform based on a 32-nanometer Atom processor.

The news prompted former Engadget editor Joshua Topolsky to observe on Twitter that Google is cozying up to Intel’s x86 platform at a time when Microsoft is adding support – for the first time in its history – for ARM’s mobile platform in Windows 8. Of course, we remember that Intel promised on numerous occasions that we’d see phones running on Intel chips in “early 2012,” even if everyone assumed the company was referring to Windows 8-powered devices. Google here wants to cover all bases with future versions of Android and it’s likely that the announcement will spark more competition between Intel and chip vendors that manufacture mobile chips based on ARM’s processor blueprints.
