Originally I thought, 12.9-inch with this resolution, then I thought 12.2-inch with 3072x2304. Time will tell, but at the end of the day we will have either of these. 12.9-inch means that the iPad Pro screen is as wide as the Air is tall, so having a different resolution would kind of bother me for this screen size, as I'm OCD. Personally, I am hoping for the other one, the 12.2 3072x2304. Don't really know why, but it seems fine.
And for those who are saying that it's a different aspect ratio, it's one column of pixels off 4:3 (2732x2049), kind of like the iPhone 5, which was one column off 16:9 (1136x639)
