I know i'm over brainstorming this whole thing but ideas are flooding in.. I think an important thing is make a roadmap for features, and we do not have to have them prepared, but planned to roll out if needed.
There is no such thing

We just need to brainstorm - so far 48hrs?? i don't think this is too long - maybe not much longer.
Prioritise / Rationalise into initial concept incorporating some USP features.
Make sure we have enough bounty / investment.
Get on with it.
