I'm hoping for an update to the eMacs in November; something like a 1.2GHz G4, DDR RAM, a 64MB graphics card, refresh rates of 85MHz+ with the two top most resolutions, and so on. Every six months or so seems to be the product cycle for other Apple products, but the eMacs weren't updated for a whole year after their introduction, so if nothing happens in November, you'll probably have to wait until May.
