I think Rock being DLC is a mixed bag imo. If it really is him then it begs the question: What are they going to do with him? Considering Astaroth carries portions of his moveset (particularly his throws), I feel they’d have to rework and introduce a new moveset for him with his axe/mace in order for him to really sell and stand out. If they can do it with Mina they can do it with Rock.
In Soul Blade/Soul Edge & SCI Rock was the original ax man, but Astaroth was favored more for story & gameplay. In SCIII & IV, Project Soul gave Rock a Mace instead of an ax, but 50% of his moveset was still identical to Astaroth's. In SCIII & IV we saw characters that use to play similar to others starting to play a little differently. I think Rock's moveset is going to be reworking to keep the Mace from SCIII & IV. Effort is going to be put into making him different from Astaroth. Project Soul has done a great job of making characters that were similar in SCI & II play differently in SCIII & up.
