well considering there have been 3 accepted orders for 08 models I would beg to say you, sir, are wrong. (I work for a Mazdaspeed dealer. this is where I have my facts, where are you getting YOUR info?)
feel free to email mazda for confirmation, but the schedule is set for an 08 model year.
and to clear up a little misinformation from another.
the MSP had 2 half year runs (03 & 03.5), ending with the retirement of the protege.
the MSMiata ran mazdaspeed models in 04 and 05, ending with the retirement of the model generation.
the MS6 ran 2 years (still current) for 06 and 07. MS6 will be ending @ the end of 07. (with a new 6 generation to be replacing current generation 6s)
the MS3 is currently on no "set" timeframe, however it had an 07 production run and is currently slated for 08 production (starting actual build roughly in june). following previous trends, its safe to assume that it will, infact, only last 2 years.
Please people, do a little research before bashing correct information
EDIT: and 1sty, the 07 MS6 was its own production run and not leftovers from 06(which would be illegal to actually sell as an 07 model).
