We recently did a kitchen reno and I wanted to pair a a new style TBD with the hidden Mac Mini on our small desk in the corner (business use). In the meantime, we've been using a U2711. To be honest, the screen is really enjoyable and probably better than the current glossy TBD because the kitchen is so bright.
If we don't hear anything on Sept 10, it's likely going to be 2014. However, new Mac Pro buyers will want new monitors; and if they go 4K, they'll need to go non-Apple. So we might be looking at 2 different monitors from Cook and Co.
Before the introduction of the Pro last WWDC, a new TBD was low priority. If you wanted that slim profile look, you had to buy a new iMac and they had enough trouble yielding them.
