That's a good point. Believe me. I love the MTx4r. I am also not looking for a new chassis or change to a different chassis. I only look at it from a dollars and cents view. Why would Mugen invest a ton of money into the release of a new 1/10 chassis when all signs say the return on invest is not very good.
My gut tells me that there will be no new chassis for awhile.

Have you notice that the MTX4R has been removed from the advertizing banner Of the Mugen Seiki web site.

AGAIN GENTLEMEN, I'M MTX4R LOVER NOT A HATTER!!!!!!

Pass you soon...
