That article makes no mention of a retina 1680x1050 BTO option (i.e. 3360x2100). Like many posters on this forum, I agree that it's time that the MBP upped the base resolution to something competitive. If they can't find a way to offer 3360x2100, then hopefully they at least maintain the 1680x1050 BTO option alongside the base retina screen.
When the 2012 is finally released, and 2880x1800 is the base res, I'm really hoping most of the reviews contain comparisons between a retina'd 2880x1800 vs. a hi-res 1680x1050. The retina gives you crisp and sharp graphics, and the same amount of space. The other gives you near-retina quality and more space.
