There will also be support for a few new devices- Acer Liquid, HTC Wildfire and Samsung Vibrant. My eye is also on the new HTC phones that are about to get released like the G2.
It looks like their doors are still open to new devs and currently unsupported devices, as well - to quote Cyanogen once more:
A lot of people ask me about adding support for their phone, but we can only support phones that we actually own. The CM team is always looking for new hackers to join up with us to add support for their favorite device. Get in touch with me if you’d like to help.
CyanogenMod is open source. The quality of code being added to CM has vastly improved because of the code review system that we’ve put in place, Gerrit. It’s the same system used by Google to manage the Android Open Source Project. It allows anyone to submit code to the project in a highly-visible way and gives us a way to examine and improve it before it’s actually merged. We want your code, so send us your patches. If there’s something you don’t like, change it.
Impressively, he also says that they're sporting a user base nearly a quarter-million users strong. Not bad at all.[Source: CyanogenMod]
