Hi DNJ
I doubt if they will ever say it publicly, but quietly they will tell you that the last 76 note arranger they made, was the biggest sales disaster in there entire arranger history, (A lot of marketing staff got their backsides (Butts) kicked) and so it is unlikely they will make the same error again. (Particularly as their research into their target market (Home Uses) shows minimal demand)
Although not confirmed, there are indications that other well known arranger manufactures are also considering dropping 76 notes.
Fingers crossed that the last paragraph is only rumour.
