Personally don't care if it goes up to 69.99+, but considering MSRP is 59.99 I doubt the pricing will change anytime soon. Also the pricing is better than what we had in the 1990's.when some games were 90-100.
However if you are worried about pricing I have an idea for YOU!!!! Pull up the consumer price index and consider showing your mother the average cost of the "special" services she provides to other people and ask her if she can spare that extra to cover the overage of your video game habits.
Thank you and have a pleasant day....
