I think most games will remain at the $60 standard, but I wonder about Nintendo's 1st party games. They've been $50 since the Gamecube but back in the N64 days they were $60 (Goldeneye launched at $70), so they may take this opportunity to hit $60 once again.
There have been games here and there in the past that have been very expensive: Back in the 8-bit era, Phantasy Star for the Sega Master System retailed for $70 ($80 at some retailers), and its Genesis sequel was $70 as well. And don't even get me started on Neo Geo game prices, which were around $200 each...
