What turns me off is releasing a game with content that's on the disc, and then the only way to unlock it is to pay for it. Final Fantasy and Marvel Vs. Capcom did that recently. At least Farsight isn't BS'ing the customer into buying the game then buying things that are already on it. They announced what their intent was and are delivering that much.
Of course I would love to see it all packed onto a disc as I know Farsight could do, but it doesn't seem to be in the business plan. Physical discs cost more money to make, and I'm sure that's a factor with download titles.
