I truly wish there was another game like Blade of Darkness, which in my opinion had the best melee combat system I've ever seen, but I highly doubt anything new will have realistic combat that is similarly deep and challenging. Action games and action-rpgs simply don't try very often at breaking away from simple hack n' slash - especially when a game is concerned about sales and not wanting to turn off the mainstream. Demon's Souls, which in addition to its stellar combat is also a solid rpg, is the only game I've played that reminds me of Blade of Darkness in terms of rewarding, deep melee combat. The Gothic series is pretty solid in that department as well (except for 3, which was a very enjoyable game post-patching but had more of a hack n' slash combat system. Also, I refuse to include 4 as a Gothic game)
