Re: Fighting, Tatics, and new gadgets of the New Batman
I never minded the Keysi style, but the reboot should definitely be different. A more agile and acrobatic Batman would be pretty awesome. And as for gadgets, I don't mind a grounded approach to gadgets once more, but it can obviously still have a more "techy" feel to it, like the gadgets used in Arkham Asylum/City, for example. Rocksteady definitely has a gritty/grounded approach that's still fantastical in almost everything in their games and that's the approach that should be with the reboot.
A horror approach? I don't think I'd be all on board with that. There could definitely be some scary elements for sure, though, especially if Scarecrow is used right.
