New 4K 21.5-inch iMac on tap for next week

Mark Gurman at 9to5Mac is reporting that "multiple reliable sources" say that new 21.5-inch iMacs sporting 4K screens will be introduced next Tuesday, October 13, 2015. While the style of the iMac will remain comparatively similar to the existing model, it will have a new 4096 x 2304 screen and faster graphics cards, and will most likely come pre-loaded with OS X El Capitan.

Gurman expects the 4K machines to come in at a slightly higher price point than their non-4K counterparts. It's not known if the new Bluetooth Keyboard and Magic Mouse 2 with Force Touch integration will arrive alongside the new machine, but it would be good timing to release the new interface devices.
