they've created a distribution model which will be very hard to move to a 2.0.
Depends on how drastic 2.0 is.
If it's just a new and improved rule set, that doesn't change any of the fundamental stats then it wouldn't be too hard. If it's a complete revamp of the system then it could very well be the death of the game...
Unless they come up with some system that lets you update your cards without having buy new expansions I just can't see how any of us who are currently playing the game could make the change. I'd be willing to pay something for v2.0 cards, but no more then $10-15 per wave or something like that.
