It's too early to say Merv, at this point it's looking something like the F22, with the advantage of a 30 year jump in the technology, it's going to be ( potentially) a very impressive aircraft indeed.
It's going to be ground breaking in all areas, using a good deal of new technology, from propulsion, to construction and avionics.
The F35 is an abstract lesson on how not to conduct a military aircraft programme, it was dogged with trouble from an early stage, in reality it did come effectively very close to failing, the technical sophistication becoming so horrendously complex and overwhelming for the contractors, but was simply too big and important to be allowed to die, so they just kept throwing money at it until it eventually worked!
It's finally starting to reach a level of operational maturity ( though full operational capability is still some way off) 28 years after the 'all things to all men' concept was first drafted!
I personally think LM can't wait to kill off F35B and C and purely concentrate on future advanced A models, it will make their life far easier.....
The F/A-XX is effectively a Gen 6 Tempest competitor, clean sheet design and it will be very interesting to see what emerges.
I feel the Franco German Spanish effort will be far less ambitious, with German continually forcing cost cutting and physical size limitations, due to French insistence on Aircraft Carrier capability.
This will also add to the costs and complexity of their machine.....
