The project has been tied for 10 years. And there's not a huge variety of aircraft available - there were only two aircraft under consideration, EADS Mako HEAT (German) and M-346 (Italian). Neither France nor Spain nor Sweden have a "modern" jet trainer under development, and no one else other than those 5 within AEJPT has the capability to build at least a high supersonic trainer.
I'm not particularly knowledgable about Military aviation, but do air forces really have a requirement for a supersonic jet trainer. I always thought that advance training was done in subsonic jets like the hawk, L39, alpha jet etc. I know the americans use the the T36 but I think thats the only purpoe built supersonic jet trainer at this time.
Having just a superficial knowledge of the Eurofighter program I just get the feeling its going to go the same way as other multi national defence projects.
European nations choose to design their own individual tanks, frigates, artillery, small arms because they have industries that are just about capable of doing it and that need the work.In the days where direct subsidies to heavy industry are forbidden by the EU its going to become more common.
Of course I'm sure you're right about there being no jet trainers in the pipeline but as soon as CASA or dornier or whoever hit a bad patch I'll be willing to bet that they'll produce something, that will of course meet their respective nations exacting requirements
