The fact is, is that the next GN'R release is highly likely to be material written and recorded, from the same sessions that the tracks from Chinese Democracy was from. DJ in my view would be adding parts here and there, much like Ron did back in 2006-8.
All people have to do is to use their common sense, if Axl is sitting on 3 albums worth of material. Why would he choose to record from scratch, and create an album that primarily features this current band.
He already has the gold, all I reckon is happening now is finishing touches and maybe some DJ overdubs to intergrate him into the project. That's why I didn't like the phrase DJ used when describing "GN'R recording everyday", because it made it seem like that the whole current band were locked in a room recording an album.
I think that the next album will be very much Chinese Democracy 2, in every aspect.
