Apple is reportedly holding an iPad mini event on Tuesday, October 23, and iMore has heard for a while that new Macs would likely be along for the ride. A 13-inch Retina MacBook Pro is one of the most likely things we'll see, and Mark Gurman from 9to5Mac has some details:
The new 13-inch MacBook Pro will be sold in two configurations, with differing processors and storage, and will be available for purchase soon after introduction.
As mentioned before, the 13-inch MacBook Pro will probably require a discreet GPU to handle Retina duties, something that makes Retina challenging for smaller machines, but has a small enough screen not to make panel pricing or yield impractical. In other words, it's the next logical candidate and should basically look like a smaller, more compact version of the current 15-inch Retina MacBook Pro.
Update: John Paczkowski of All Things D is also reporting on the new 13-inch Mac Book Pro:
The machine, a 13-inch version of the 15-inch MacBook Pro with Retina Display that debuted in June, will feature the same thin chassis, all-Flash storage and a 2,560-by-1,600 pixel density display comparable to the 2880-by-1800 pixel of its predecessor, sources say. No word yet on price, though it will obviously be a bit less than $2,199 base-line price of the 15-incher.
New Mac minis and new iMacs should also make an appearance. WeiPhone.com posted some interesting possible details about those this weekend. (Google translated).
the the new imac design has epoch-making significance. The innovations include: the side from the side almost can not see the imac's thickness, similar to water droplets curved design tetragonal type than it is now almost completely different. Process, the screen the special glue "sticky" on the panel in front with a special glass attached to the surface, very beautiful. Narrow design, but the bottom of the front is still wide-brimmed design. The bracket made some changes. Stronger performance, the price will be more expensive than the current imac. The first release of the 21-inch product, the follow-up to re-introduce the 27-inch.
So, take a Retina MacBook Pro-style display, extend the chin down and widen the base as minimally as possible to fit the actual computer components, and... profit.
Update: More on the aforementioned new Mac mini from Mark Gurman at 9to5Mac
Alongside the smaller iPad, Apple plans to announce a new version of its Mac mini. Sources say that these Mac minis will come in two standard configurations, with different storage and processor options, and a third model that runs OS X Server.
We should find out more in just over a week.
