You do realize that Square Enix confirmed it was going to be an episodic release, right? It's not going to be a full game like the original, they said it themselves:
Yes I do realize that. But they also had a gameplay trailer of the game months before that of a build that was canned and they restarted development pretty much completely. The gaming industry in general has proven that episodic releases which were once big are quite often a disaster and there is only one series I can think of that still pulls it off (A Square Enix series, but they also had bad luck with Hitman so). I just do not see them sticking with an episodic release system.
