Hitorque--You may be correct that he might want to sell, but "I" think you are wrong on a few other points.

#1-Yes the 55 has been dropped, but is being replaced by the 58.
#2-Keith has other engines in development, that I am not at liberty to talk about.
#3-Might I ask where you have obtained your information??????

Maybe my understanding of the last conversation I had with Keith was wrong, but I doubt it.
