So basically he's remaking the game and it'll take another 6 months just to see a big update before he moves the story forward another year wait...so close to the end of the main story...
That will depend, but no it shouldnt. I myself, am thinking of actually starting a new game once it does drop, as I've forgotten many details of the story and would like to see it all in a fresh coat of paint. But theoretically, you should be able to continue on as if nothing happened
