Considering that everything pretty much requires membership. I'm really interested to see how they're going to do this if the game is going to be a free to play game. They're going to have to really hope people find F2P compelling enough that they may want to consider subscribing.
But make no mistake. I think this is great. I can't stress enough how happy this makes me that the game will be on the largest gaming platform in the world for everyone to see.
But I am concerned that worlds with a player cap of 1500 are already struggling when there are 400 or more on the server. Turning up the heat on a pot that's already boiling over sounds like a bad idea in my mind.
