Evidence suggests that Apple is preparing to refresh its MacBook Pro notebook line. It's said that a Best Buy employee uploaded images to a forum that show the current 13.3-inch MacBook Pro with a 2.26GHz Intel Core 2 Duo has been removed from the company's database.
Additionally, GeekBench results have surfaced for what appears to be an Intel Core i7-based MacBook Pro running an unreleased version of Mac OS 10.6.2 (build 10C3067) and BIOS MBP61.88Z.004C.B00.1001251657. Also, Amazon has reduced prices on existing MacBook Pro systems to below minimum advertised prices.
Most expect the refresh to bring new systems based on Intel's Core i5 processor, which agrees with a promotional blunder last month that mistakenly offered such a system as a prize. It seems likely that if a refresh is coming, it'll arrive soon, so stay tuned.
