Just because there's no 2D cockpit doesn't mean there's no 2D cockpit functionality. The "2" view gives you the snap views using the 3D cockpit, and I think it looks better than the 2D cockpit, especially with the new lighting effects.
The only thing to be missed is the kneeboard, but that is a planned re-insertion in a future patch. In the meantime, you can use
Weapon Delivery Planner and print out your kneeboard or display it on a second monitor. If you have a notebook, you can use WDP in networked mode as well.
