Lyman started the game, I guess someone else will finish it, but it will follow his framework since they're not going to throw away what was done already.
I feel bad for Lyman though, his post seems really down on everything.
I had heard previously that TWD code was delayed BECAUSE of Spike. He's probably doing nuts & bolts framework type stuff for it.
The game is missing big chunks, so it will obviously get at least 1 more big update, but it will be a shame if we lose that Lyman polish.
