Welcome to a.net.
After the 737MAX engineering is completed, look for Boeing to move into increasing R&D for the 737 replacement aircraft, which I predict will enter service in the 2025 timeframe. While the MAX will be a successful aircraft, I don't think it will be as long-lived as the NG
Ditto the A320NEO and whatever comes after it.
As far as widebodies go, the 787-10 and 777X will consume all of Boeing's attention for the foreseeable future. There will be no further widebody development at Boeing for twenty years, if you ask me.
For Airbus, the A350 should carry them through the next 15 years. We've reached a point at which aerospace development is at an odd place: the big changes that are left are unappealing (blended wing-body, bleedless airframe, etc), which leaves just minor step changes in engine and aerodynamic efficiency. If you look at the 787, which is the most efficient airframe Boeing is capable of producing in its size class, you see that we're just about at the pinnacle of where we can go in that field.
So, all that to say, the next changes will either be material advances (composites, a la 787 and A350), or continued improvement in engine design.

I was once excited about the boeing yellowstone program and the possibility of new clean sheet revolutionary futuristic designs. However, we are apparantly stuck into the tube/wing concept.
Yep. While the futuristic stuff (like EasyJet's proposed unducted fan narrowbody) is exciting, we're locked into more and more of what we've already got. Until SOMEONE gets REALLY BRAVE!
