Of course they did. First, it would look confusing and unprofessional for customers to have two different versions of FF14 in stores. Secondly, SE wants to sell the new version at 50 bucks a piece, probably. And thirdly, if lots of people bought V1 now because they were planning on getting V2, that would mean a lot more people would be downloading the full new client from SEs servers, which means they would either have to pay for more mirrors, or have everyone's download speeds suffer.

And if you haven't bought the game by now (it's been sitting at $10 for quite a while), I don't think you were that interested in it in the first place.
