First off, it will be CM10 not CM 9.1 or something else. They fully expect the ‘Prject Butter’ aspect of the new code to be a fairly painless merging experience. Next, they are currently fully expecting that any and all devices that can and will support CM9 will in fact be eligible for CM10. And the most important question, ETA.. Well, that is one you just don’t ask about.
Google is expected to release the Jelly Bean source code in the middle of July. Once that has been pushed out then the CM team will get to cracking and see whats up. Hopefully we will start to see some CM10 nightlies rolling out to a plethora of devices in only a few short days. Until then, sit back, relax and know that even though your carrier and the manufacture might be failing at their jobs, the CyanogenMOD team has your back.
