something curious about new nvidia mobile cards

I was exploring new nvidia cards on nvidia website, when I noticed something curious about a few nvidia mobile cards. The max dvi resolution of gtx 660m, gt 650m, gt 640m and gt 640m LE IS NOT 2560x1600 like all other cards. It is 3840x2160 instead. I am thinking about new macbook series.
On AMD side there is no mobile card supporting such resolution, so my opinion is taht new macbook pro will have some of these cards.

yes, that's what I thought

My 660M is for a 3D display. Wonder if it's for left eye/right eye rendering at 1920x1080.
