From what I have seen and heard, yes it is.
I have not had the chance to get my hands on one physically yet.
I mean that from the advertising and the demos I heard, the Audya might just be a bit better.
Hard to tell really as I have not personally played either.

[Edited to add]..also Roland in Australia will still not come to the party and drop their prices on the G70..out here it is still $4400 (about 4100 USD) and they will not budge..
The shop I deal with (a big roland dealer too) and I have been trying for months..with news of the new arranger I thought it was a good chance they will drop, but that is now not happening so I guess the prices will stay the same.
You guys over there really have it good when it comes to buying music gear!!
