Got a reply from OS to my email:
"Mr. Sprankling
Very sorry for our late reply.
Thank you for your interest in our new FS-70 Ultimate engine.
A production will be completed between end of July and early August. We will ship to our distributors as soon as completed.
We thank you in advance for your patience for a while.
With kind regards
N. Shiomaki O.S."
Hopefully wont have to wait too long before they hit the streets.
