So originally I wrote: "Two things 1. Ivy Bridges have been delayed "until after June" for mass production. 2. OSX Moutain Lion will be release in the late summer ie. probably late August. Knowing that the new line of Macbook Pro will probably be streamlined with the Macbook Air and so that they will be released together, we can bet that the next release will be for September the soonest." But after reading a bit more, it is true that September is way too far and people have been waiting for an update as the demand for new Macs is decreasing in this first quarter. Plus the critical point about this update really is the Ivy Bridge, so if the supposed "exclusivity" Apple may have on the first batch is true, it very possible that an update is imminent, maybe during the March presentation of the iPad 3.
