I'm just hoping some of the strategy from the EXE series' battle system comes back. I always loved how deep it was despite the restrictions. EXE 3 was absolutely brilliant in terms of deck versatility, fluidity with the amount of mega chips, program advances, and how the Navi Customizer worked. The Mod Codes you get later in the game were outstanding and if used right would make the HubBat an absolute must, especially as it negates the 50% HP loss clause normally put in by the ability.
I say I'm indifferent but I'll still probably wind up picking this up. I've gone through the main six EXE games along with network transmission and have gone through two of the three star forces, with the third on the way as soon as it drops. Here's hoping they take into consideration EXE3s system with some refinements in styles/forms seen in EXE5 and 6.
