While not likely they will change it again, there is always a small chance.

The upper deck in Asiana's 747 is pretty good. Loads of leg room, tons of storage space with the side bins. Almost never any babies or children up there. There may be a bit of noise from the galley in the back, but 11AB is just fine. The upper deck is, for the most part, a good experience. Seats can recline to almost flat, but at an angle.
