CoC2 
isn't going to be done in two years and even if they do make a CoC3, it's extremely unlikely that it would happen right after development of this game finishes. CoC2 had a couple years of behind the scenes discussions and planning before it got revealed to us, so even 
if the core team decided they wanted to do CoC3 
and make it their next project (and not, say, take a breather and do something different, shorter or both in between) there would still be a break between the door closing on CoC2 and anything happening on CoC3. So y'know, don't hold your breath. 
Oh and by the way:
We know for a fact that 
this isn't happening even if Savin does make a CoC3 some day. Which you 
really should know already considering that you asked Savin directly and he told you no, just two weeks ago.
