[DOUBT]Is CM12.1 a real possibility?

Hi guys, I'm thinking of buying a OP2, and yesterday I recieved my invite, but I don't want Oxygen OS because I usually do hard modding stuff, so I would need at least CM12.1 and starting from there maybe a ROM like RR or AOKP.

But the CM development is still in process. So my question is, it's real thing for sure in time (I don't care how much time)? Or it may be the possibility that CM never comes??

Thanks.
