yThe RAZR has already been confirmed to get ICS. HTC has said it will upgrade as many devices as possible to ICS - whatever that means. Google says ICS can theoretically run on any device running Gingerbread (Android 2.3). No doubt some 2.3 units will get left behind but quite few should get ICS directly from the OEM. Others will be upgradeable via custom ROMs. Basically, if you have a phone with about a 1GHz or so processor and 512mb ram ICS should run great.

ICS will not kill the N9. MS and Elop didn't abort the baby, but they made sure it was stillborn. Just short of 1st degree murder but worse than manslaughter.
