I don't know who this Pachi guy is, but my understanding of what Daisuke wanted the GG series to go towards has very little to do with Pachi's "vision" of where he wants it to go.
Daisuke has already expressed his hatred for Soul Calibur type games, and there's been a few chuckles here and there with how Street Fighter IV has presented itself.
Honestly I don't think Guilty Gear should go the route SSFIV has gone. Overture-styled games are one thing, and if he wanted to do battle simulations that more closely resembled the Crusades, that's fine and dandy. But the fighting games were extremely unique in that number one, they were based on Daisuke's design and vision of where it went and the story and everything that went with it. Number two...any input Daisuke had in latter games wasn't so much second hand as it was that they had a general idea where to go with the games updates and changes and just asked his advice here and there (kinda like how Hideo Kojima does his Metal Gear games).
On top of this, how Guilty Gear ends up is highly dependant on how successfull BlazBlue becomes. A lot of the things they "tried" in Guilty Gear, were "revised" in BlazBlue and ramped up. Not only that, but the visuals, techniques, methodology, that we consider "common" for BlazBlue when it was developed, would be extremely renovative when applied to Guilty Gear. Story-telling methods, visual representation, vocal representation, so many other little things that they learned when developing BlazBlue...even the very concept of revising the in-game system in the form of "Version patches" is a new concept.
I think the real issue is, too many people are thinking about GG from a gamer's standpoint and not a developer's standpoint. Sure, profit margin is one thing, and BB is the current money-maker.
The very concept of Slashbacks, FRCs, etc, are going to seem outdated with time anyway. Instant Blocking and use of Barrier, as well as changing how Rapid Cancels actually work (hell they even work with Jin's projectiles). So many other things are coming to the fore in how a fighting game can be played, including gimmicks. Even complicated curse combinations are being regulated and simplified (imagine applying Arakune's curse combo system to Testament!).
There's more than that that can be said, but the jist is this: what they think of GG now is still that: just a thought. Things change over time, and what you expect and hope for changes just as dramatically.
Daisuke originally planned GG to be a 3D fighting game...but this got turned on its ear. So I'm not going to put much stock in a single employee's opinion, since Arc Sys works as a team anyway.
