iMac Refresh Next Week?

According to industry tipsters, Apple is planning on releasing an updated iMac next week.  Other than that details are somewhat sketchy, but here's what we do know:

"Apple is known to be developing a Penryn-based refresh of both the iMac and its Mac mini cousin for the spring, delivering the cooler-running and faster processors to systems that haven't been updated since August of 2007."

We wouldn't be surprised if Apple also included a higher end graphics option for the high end models.
