Is it the one he plays on the Tokyo G3 dvd??
He has a couple for himself i believe as he wrote a small number of songs on a 7 a few years back (on Strange Beautiful Music and Is There Love In Space). He doesn't play them now, no 7 string songs on the last 2 albums. I would guess the chances of it being released are zero at best
Shame, i'd love to try one!!

Get past the band intro and he changes to his 7 string
