A new generation of iMacs may be on the way. Supplies of the popular all-in-one computer are reportedly dwindling, a practice that usually occurs right before a line is updated. According to a 9to5Mac tipster, supplies are tight in most markets, with one large market having not ETA for new shipments of the computer.

New iMacs with Sandy Bridge processors and Thunderbolt I/O ports have previously been rumored to be launching later this month.

Are any of you waiting for a new iMac? What kind of updates would you like to see on the computer?
