Very cool...
I'm afraid it dwarfs the FX X-Wing in my view... X-Wings are fair sized ships for fighters, as far as overall area they take up, though they're kinda compact in the actual ammount of "steel" there is going on there, but anyway the TIE's bigger suffice it to say just because it's like a big cube basically.
Looks sweet though...
I wish Hasbro would just do resculpted to-scale vehicles and charge appropriately for them. Scale AT-ST, Scale Snowspeeder, Scale Y-Wing, Scale X-Wing... Forget about the "big" things like AT-AT's, Sandcrawler's or anything that isn't even made yet that's in the "just too big" and simply put out definitive versions of the ships they CAN acheive something great on. This TIE Fighter just makes me long for that.
