According to a guy I know who went to E3 From had it at the show and they were acting really goddamn vague about it. Sort of like "Possibly in the immediate distant future of tomorrow 1st, 2nd, 3rd, or 4th quarter." I know From doesn't have a US arm so if anything Agetec may release it or somebody else. I'm pegging Agetec mostly because its fairly close to Armored Core which they sort of cornered the market on.
I don't think I mentioned this before but, honest to god, this game supports that Thrustmaster Top Gun flight stick thingy. It has an ad slipped in with it for playing it with the controller and if you go to options in the game the controls can be mapped for it.
Also, it looks like I'm not exactly at the end of the game. According to a recent faq I got about 5 levels left. I'm stuck on this nasty one that has you chasing 3 ARKs through an Oil refinery. I also looked at a couple of message boards and there's a music mode mode and a mode that unlocks all of the game's movies, including the debut trailer from the 2001 TGS, on top of completing Free and Expert modes with grades at least A.
So far I likey a lot.

The only things that need improvement maybe the lock on featue, which doesn't allow you to change targets when you have a bunch of scumy little bastards protecting the ARK, and possibly a VS. mode. Other than that its aout what I was hoping for.
