I have speculated on the Saab/Boeing T-X in the past. So far, nothing seems to confirm or deny my guesstimates.
Saab and Boeing have been tight-lipped about about their upcoming trainer. So much so that a recent conference display was by invitation only. Its only release to the general public is the vague shot of the aircraft's nose that you see above.
While all this secrecy is infuriating to aviation buffs, its not entirely unexpected. Saab and Boeing are taking the T-X competition very seriously and it does not want to give away too much to their competition. Saab's CEO seems quite confident in the design however, and looks forward to cooperating with Boeing in the future.

Time will tell what the rest of the aircraft will look like. Will it be canard-delta design like the Gripen? A pelikan tail like that pictured in the early Boeing render?
