The official site has updated again. This time there's an official trailer up that looks REALLY good. The touchscreen controls in particular look great, and battle animations load at the top screen while the bottom screen stays on the map view at all times. :D

Also, there's an update on new graphical effects for chaff grenades, flash grenades, smoke grenades and acid bombs.
There's also a new difficulty setting for New Game+, whereby you can select to increase enemy strength by x0.5, x1.0 or x1.2.
