Will Apple announce new hardware sooner than expected? Mac Rumors writes an internal AppleCare memo reveals new SKUs will be announced on Tuesday, December 8 at approximately 5:30 a.m. Pacific Time. There are no further details so it's unknown what to expect. It seems a little early for extra Mac SKUs so perhaps the announcement will be something minor.
Given that AppleCare changes are expected, it is likely that any product(s) announced next Tuesday would have AppleCare+ coverage available, so we could be looking at new hardware. However, in the interest of tempering expectations, it is possible that the announcement could be for a minor accessory, or that no announcement transpires at all.
