SavIP was meant as a "proof of concept" for CoC2, and was written in a way that the CoC IP could be applied with a few minor edits (ie, the Demon King becoming Lethice the Demon Queen, etc.). But yeah, now that CoC is actually ~done~ish and I have secured Based Code Dragon, well...
Nah, nah. SavIP was years and years ago (and was abandoned because lol coding hahaha). CoC2 is happening as CoC2.
Good guess.
The sheer, massive differences in CoC's epilogues (not to mention how sweeping and expansive they are -- some taking place over generations) makes a direct continuation pretty much impossible. At least without screwing half the audience and choosing a "canon" ending.
:3
Can say with some confidence most of what was in SavIP (mobs, characters, locations) will be making the transition. Though the context for them will be fairly different.
