Why wouldn't they be?
TN said they're making characters more individualized now, adding stats in just for kicks would be pointless.
Besides, with the gameplay footage we've seen from E3 you can tell that these stats have been implemented when each character was being revamped for DOA5.
Actually, this would make a good question for Dr.Dogg and Rikuto.

Strike, Throw and Hold ratings tell us how good each character is at the different points of the triangle system. We haven't been told exactly what this entails yet though, but we can probably guess.
Power rates the damage of attacks and Speed rates a character's movement and attacking speed.
The
Moves category has pretty much already been explained, it pertains to things along the lines of evasion and mixup game. Pretty much things like stances, sabaki and moves that have dodge-like properties upon execution (think Kokoro's

).
