Think how much would it cost, don't even know if they make them at all, then think about the battery drain and the graphic power required to drive it.
And as others said you don't even need 300dpi if you look at the screen from 15+ inches.
Besides, on OS X text gets tiny very fast upping the resolution on a laptop screen, unless 10.7 has a resolution independent UI you won't see any more than 1080p at max on a 15".
Actually, in my opinion you only need 150ppi to be considered "Retina" on a 15.4" laptop, since normally you would hold a laptop that size about twice the distance from your face as you would an iPhone.
WUXGA 1920x1200 in the 15.4" would provide a nice "Retina" display (~150ppi), and could be (at least) offered as a CTO option.
Imagine something like:
* MacBook Pro 15-inch Glossy Widescreen Display
* MacBook Pro 15-inch Hi-Res Glossy Widescreen Display [Add $100.00]
* MacBook Pro 15-inch Hi-Res Antiglare Widescreen Display [Add $150.00]
* MacBook Pro 15-inch Glossy Widescreen Retina Display [Add $200.00]
* MacBook Pro 15-inch Antiglare Widescreen Retina Display [Add $250.00]
If they went 16:9 they'd need 2048x1152 (QWXGA) in 15.6" to reach 150ppi. If so, then I'd happily order just the display panel, and replace the 1920x1080 display in my Dell E6510 :3
(assuming it uses the same connector, places the connector in the same position on the back of the panel, and is LED-backlit)
(btw QWXGA != WQXGA. There are a few ~23" monitors with the QWXGA resolution)
As for the 17" MacBook Pro, unless they use WQXGA 2560x1600@177ppi (which is highly unlikely), they would probably have to "invent" a new resolution between WUXGA and WQXGA such as 2160x1350 or 2176x1360 (which is also unlikely)
The text shouldn't be too small, because I have an old Thinkpad T42p with a 15.0" 2048x1536 display (mod) @171ppi and I love it.
....and if an old 2005 ATI FireGL T2 GPU can sucessfully power that display, and the laptop battery lasts a good solid 4 hours at the same time, I see no problem implementing ultra-high-resolution displays in the next macbook pros.
