People are just now happy to spend cash little and often. The current market has mainly kids wanted to buy tiny packs of cosmetic crap because they're 99p, not because it's cost effective.
I think Season Passes will now either turn into something similar to this CoD approach or it will be a cheaper Season Pass that can't be much more than £/$30. The average gamer will still associate anything above that figure as a 'New game' and if they physically or digitally don't get that, then they are immediately disappointed.
It's just be nice to know if microtransactions actually went back into the game, abit like a post-live crowdfunder so you knew if everyone raised money in game via these, when targets get hit then you know content later down the line gets created. You can dream, eh.
