I think I saw a few games already get discounts, Ryse for example I think dropped down by $10... I'ma go check. I know there was a great deal on Tomb Raider (it was like 50% off or something decent like that) but I'd already played it a few times through on the PC so it was one of those greedy purchases that basically had me staring at the xbox store page for it multiple times and the later it was in the night the more closely I was to jumped at buying it again... thankfully I didn't, I prolly can't afford to buy games over and over again just cause I want something to play on my new shiny thing.
Ryse is in fact $10 cheaper right now, seems to be a weird discount (original price is strikethrough but there isn't any indication it will go up again). Most other games are still full price though sadly... even my beloved and once cheap tomb raider is back up to the insane full price it shouldn't be at right now :(
