Sorry guys. From a mazda insider (not me but someone else) the rotary is not making it into the miata. And really, should we? I mean, part of the joy is revving the little 4 cylinders like mad. The rotary just doesnt make the noise or the feel that 1.8 (or the 2.0) makes. Not to mention the 05 mazdaspeed miata doesnt feel ANYTHIGN like the 06 miata 2.0.. OMG. so nice.
