AppleInsider reports that Apple has begun warning resellers that new orders for the high-end 24-inch iMac may not be filled due to decreasing supplies. Let's look at what we know about a possible iMac refresh.
We'd heard rumblings before, but if true, this warning is a pretty clear indication of a refresh. The current iMac line, released in late April 2008, probably isn't due for any kind of massive redesign. The most obvious reason is that it just isn't very old, especially compared to its nearly-senile relative, the Mac Mini. There also haven't been many rumors floating around about new iMacs, but it does look likely that the desktops will get a bump from dual- to quad-core procs in time for the release of Snow Leopard.
