As for the resolution of the new Retina iMac, OS X Yosemite betas include references to 6400 x 3600, 5760×3240, and 4096×2304 resolution screens. Apple has been rumored to be working on a 5K iMac display for launch later this year, so perhaps that’s the direction Apple will take, and a recently introduced DisplayPort standard update could make this a reality.
Sources say Apple is also working to update iMovie and Final Cut Pro with better tools for editing 4K footage.
The new iMac will likely launch alongside the regular version desktop as a higher priced variant, similar to what Apple did with the MacBook Pro.
Apple is also rumored to finally be releasing an update to the Mac mini and a new iPad Air. Perhaps we'll see another Apple event next month announcing the new hardware.
