But how it is "shafting the cosnumer"?
If anything, it's shafting:
A. Potential resellers (that will need to lower the price)
B. People that rent (multiple times or for extended period of times, since there's only a 2 day trial)
But:
A. People that buy the game new, get the pass and don't need to pay anything else.
B. People that buy the game used, they're probably buying it used because they got it for really cheap. So if they get the game for $30 and then pay for the pass ($10) is still $40. And compared to a $60 there's still some savings on it.
If people are buying used to get $5 savings of a new price, sorry but they're doing it wrong. Even $10 is not that much of a difference if the game originally costs $60.
$10 more expensive? Last time I checked MK costs $59.99, which is the MSRP of most current gen games. And is not like before this announcement the game was going to cost $49.99
