Sounds like a precautionary statement to judge fan reaction to the reintroduction of Episodic content, which worked so well last time
(I'm still waiting for Half-Life 2 - Episode 3 - yes I know it'll never happen). Maybe a better idea is to roll out a alpha demo first to gauge reaction and then go from there depending on what people think of it? To be honest though I've never had a problem with the traditional way its always been in the industry (as in make a full game as good as you possibly can, possibly supply a pre-launch demo and if the game does well make a sequel if you want to).
