Which is why I'd rather have a statement with facts from a team member instead of some feelings and guess-work from the choir.
With all due respect. I'm part of this choir, or I wouldn't have spent time on the forum.

then simply wait for their statement, if they care, instead of accusing everybody else of being bat-shit crazy, pulling from the air, retarded or whatever. people, with apparently more experience, have tried to explain things to you, but it doesnt arrive, obviously. im not sure whose fault is this.

  Not exactly. Chip RAM is theoretically most important memory inside Amiga. It's basic memory inside Amiga. That's why when You want to play Super Frog You still need to jump to Amiga standard Video output. Of course when AGA will be implemented and enchanced by team I think there will not be necessary to split memory to Chip/Fast/Slow etc. Just many MB of Chip RAM. But someone from team should say something about that, but in my opinion it should go this direction.
 

 
  Never did I question it's importance at all. However, beside playing whdload games or custom chipset games and running audio do you really need more than 2 MB Chip RAM? It does not help at all or lose at all to merge chip ram or not merge chip ram with fast ram at all. The focus should be on the fast ram for modern software and games to be honest, after all chip ram is slow so having to have chip ram have 1 GB does not help me at all. Look at winUAE you can have 1 GB CHIP RAM with like 2 Ghz RAM speed and not a single game or app used in winUAE uses that chip ram...why bother if you have fast ram?
 
  If you start disabling it and having it merge with fast ram as chip ram you literally watering out Amiga's personality and rendering what is already working fine chips to be now useless and redundant. I like Vampire as an accelerator and not as that fish in the water with a light bolb where male fishes simply leach on the body of the female fish and simply fade away as nothing more than testicles. Don't turn Amiga's motherboard as nothing more than I/O for vampire...let her be a working Amiga with an accelerator as much as A1200 with 68060 accelerator. I mean if you are so immenent on this...then I don't care having it on v1200 and up....heck....I don't care if it is even for v500 and v600 as long mine is left alone. I do not care what people want or think...as long as my baby is the way I want it...I am fine.

So you're telling me there's no remapping in the Vampire and it utilizes the bottleneck legacy chipmem instead of the Vampire onboard memory? That sounds very strange to me. Any team members that care to answer the question?

Already discussed in CLICK HERE 
APOLLO does cache fast-mem, but does NOT cache IO/Chipmem.
This means a Floppy-DMA writing to Chipmem will go to chipmem.
But Apollo will not cache chipmem.

The fact is that the AMIGA chipset bus and the 680x0 CPU Bus in the Amiga are not fully connected.

The CPU can _NOT_ see DMA writes of the Chipset.
Therefore its impossible for any CPU or Accelerator in the AMIGA to snoop them.

I'm almost agree with You :)
But I think ppl want (and team too) to move forward with Amiga Chips. Making for example, newAGA better and better (better than 1000000000000.... x AGA i wish You all) is a natural way of Amiga development. Now We have 2 not compatible video outputs (OCS/ECS/AGA and RTG). Going this way We will have always old amiga on the board and new things next to it. Of course it cannot be changed in classic amiga due to hardware limitations. But in standalone system? Why not?
Or mayby I'm wrong?

In standalone only I am 100% agreeing with you. :)
