alright, here's my view...
1) if anyone was going to come out with a kit, it would Unicraft (maker of the wild and wonderful aerospace models such as a SpaceShipOne, Boeing Bird of Prey....etc) (Possibly revell...if we beg enough, or some small company like Lindbergh --> ID4 Alien attacker...etc.)
2) If Mr. Wong was to make a model...it would cost a fortune. His models are PACKED with detail. (I know from experience). Not implying anything bad here. Plus the Talon in 1/48 would be slightly larger than even a 1/48 F-18E...if you looked on the carrier during the movie, you would have noticed the regular carrier aircraft sitting in the background. (Perfect size comparison). This would make it a fairly large model.
