If Pokemon Gray is going to be released, it should be more than just a mingling of Black and White. When I tried out Pokemon Platinum, it was pretty awesome, but apart from the rematches, Pokemon, and the battle facilities, it was pretty similar to Pokemon Diamond. Pokemon Gray should be "hey, we forgot Pokemon A in BW, so let's ditch Pokemon B for A in Gray" and "let's bring back something from previous Pokemon games that we ditched", not "modify the maps, change the trainers, and add new competitive places".
My thought of the third version of the fifth generation is that it should not be too similar to the original pair.
