JSFfan, well I know BAE are working on 'Taranis'; which would fill the stealthy, deep strike capability of the F35 pretty well...it doesn't have to contend with humans (and all the many performance limitations and aircraft complexities that entails), a lift fan or a million and one different specifications from different services. And I think it's due to fly this year.
As for the development of an aircraft that can hoover up information and then distribute it to all his pals in the airspace, I don't see why that couldn't be integrated into later model 'eurocanards' as you put it.
