By sticking with it's "one flight deck fits all" policy, Airbus is actually commiting all it's furture aircraft to 80's compatible technology.
Oh come on. The 777 cockpit is based on the 747-400, and is very advanced. The 7E7 is likely to have a similar cockpit to the 777 because it's what airlines want: commonality.
But commonality doesn't exclude innovation. It's as much about the way systems work as what the cockpit actually looks like.
Pray, how can you say that
this (A380 cockpit) is 80s technology?
It may look similar to
this (A340) but rest assured it's right up to date.
Also, the A380 will make extensive use of new materials in construction (including an increased use of GLARE than previously planned).
The big problem with the 7E7 is that most of the op. cost improvements come from the engine technologies. Now, engine manufacturers are not going to torpedo potentially 50% of their sales by exclusivising this technology to Boeing, so what's to stop Airbus hanging these new engines off an A330 (already a highly efficient airframe). Bang goes Boeing's advantage........
