The rumours are suggesting that the new iMac will be more expensive than the current model. Could it be because of: 1. Screen 2. SSD standard 3. Expensive mobile GPU like the 680m 4. All of the above I personally hope to see an SSD and a decent mobile GPU. Considering that the MBP is sporting a mobile nvidia GPU and the amount of work nvidia has done to make drivers for ML, it's a safe bet that the iMac will get something from nvidia. But which one? The 680m would make me very happy, but it is very expensive.
