Man, I think it's still too early for a new version, but.. oh well, it's looking alright. They better really focus on tweaking those "groove" options.
Honestly though, I really don't see what's the need for making rushdown even stronger by implementing a Guard Meter...
How does it make sense for Roa to be in the game now? From what I understand, the fears originated from the events of Tsukihime. Back then who exactly was suspecting Roa to be the killer? Only Ciel and Arcueid even knew about him before Tsukihime, and Shiki only just about met him in the final confrontations. I don't see him suddenly having the status of Nero or Warc/Nanaya and becoming a fear.
Also, Reize is interesting. Her appearence in V.Sion's Last Arc was a manifestation of Sion's awakening as a Tatari. If now she's a formal character, that could mean that Sion eventually becomes fully Tatari, enough for Reize to become a Fear-like entity. On that note, it'd be interesting to see V.Sion take more of a central spot in the new story and game (and also beef her up a bit please, some of us actually do use her).
Finally, I don't care about the maids, but really.. single-maids are definitely the most redundant characters in the game. If the developers were even considering removing any character redundancy, they'll get rid of the single maids. Like Jux said, they can just keep all the moves/properties and make assists a new motion. We can deal with that, right? -_-
