A scheduled maintenance update for MobileMe this evening may bring about a series of upgrades timed to coincide with the launch of the iPhone 4 next week.

While push has already been present on the server side and on iOS devices, the update would represent its first obvious presence in the webmail client and a closer parity to Gmail, where it already exists.
