This is the only thing I've ever really found picture wise.
But it's still up to speculation obviously. I've heard talk of a new rx7 in 2006, which would make sense considering the widely popular sales of the rx8 will start dropping around that time. I think they'll be turbocharging rx8s sometime in 2005 -2006 then producing the new rx7s in 2007 personally. something along those lines, but then again nothing is confirmed. I'm just speculating on business sense.
It would make my day to have a new rx7 with the improved renesis to smoke all of these trash talking new cars.
