It appears one other source caught wind of the Powerbook updates at MacWorld San Francisco... Computer Arts Magazine's December 2002 issue contained a Calender of upcoming events. In it, they wrote:
- Will Macmeister Steve Jobs be unveiling new PowerBook laptops at the Macworld show?
Reliability of the magazine's sources may be variable, as they also pegged QuarkXPress 6 for Mac OS X due in January in the same issue. (ThinkSecret provided a small preview of Quark 6 today.)
Of particular interest is Computer Arts' calender for February 2003: February 14th has an entry reporting "New Apple 19-inch widescreen LCD in shops soon" and February 24th: "New IBM PowerPC chips soon to be rolling off the production line".
Recent information over the past 24 hours brings to light the possibility of a 20.1" Apple Display with information leaked yesterday. That information has since been pulled from TCO's website. This Computer Arts article targets the date a bit more specifically... at Feb. 14th.
MacOSRumors claims they have details of the 20.1 inch display - to be priced at $1799 with a 1600x1024 resolution.
The significance of the IBM PowerPC comment is still unclear, with all previous signs pointing to volume production of the anticipated IBM PowerPC 970 being second half of 2003.
Scan of the Computer Arts' calender is available here.
Update: As andyduncan points out, the lead time to the December issue could have easily been before the November 6th announcement... which means it may have been left-overs from previous Powerbook rumors.
