I agree Diki, pretty much everything Spalding is after is already on the PA2x, except as you say speakers..I do know the RRP in Australia is to be $5995, but street will be around the $4200 mark (which is about 3950-4050 US depending on current exchange rate) so it certainly is priced well.So his wishlist is definitely do-able, its just if a manufacturer wants to..
As an aside to your earlier post Diki, I was looking at a s/h g1000 out here a while back and I went to the Roland site to check it out further, and some of the things it could do wold be extremely well placed on a new model..Maybe that's the upgrade path Roland should look at as you suggested.
