Marty,
This subject was brought up at Jason's Seminar on PS3 upgrades Friday. Jason mentioned that MTH is proceeding with the 3/2 board in Diesel Upgrade - BUT - the existing Diesel Upgrade kit will remain in inventory. Users could order whichever kit they wanted.
Also brought up was the lack of 6-32 nut recesses in the mounting bracket. Jason said they are aware of it and will correct it. I brought up that the speaker wire, p/n BC-0000008 was wired in reverse. It should not matter since the speaker coil is isolated, but I reversed the leads in that wire in the PS3 Diesel upgrade on my test bench now.
Glad you brought the subject up.
