This is the first I've seen of this possibility... According to this EETimes.com article:
The company is also expected to offer dual processor versions of the iMac for the first time, though those models might not be unveiled until an event in Tokyo later this year.
Later, they mention that possibly all systems except Laptops would go to dual processors. Personally, I've thought moving all PowerMac's to duals would be a promising way to bump speed with lagging PPC development (mhz wise).... but would iMac customers want this? And would they want to pay the extra $$$ that would be built into the price of dual-processor iMacs?
Also mentioned is the possibility of an even larger Cinema Display:
In addition to the desktops, Apple is expected to roll out a new high-end desktop LCD monitor. The existing 22-inch Apple Cinema Display, which sports a 1,600 x 1,024 resolution, will be superceded by a model with a 2,048 x 1,280 display.
