A possible release date has been announced, here is a copy of an email I got from DIYautotune.
"Just wanted to give you an update on the Grand National MSPNP. We have set an October 15 release date for it. Final pricing has not been announced yet, but it's going to be in the same vicinity as the existing MSPNP Pro units in the $1199 to $1599 range. I will send more details when they are available. I can tell you that it will have the same 7" x 6" x 2" external dimensions as the units we make for Miatas. Spare I/O will be on a 26 pin connector on the opposite side from the main harness connector.
