They went lightweight on the cooling system, but as long as the radiator and hoses stay intact it does a fine job of keeping temps under control. The biggest problem with FD reliability is the sequential turbo control system, all the hoses and solenoids bake in the extreme heat, pop-off and eventually disintegrate. Leading to complaints like, "my primary doesn't work", "my secondary doesn't work", "my car is slow", etc... A turbo trying to maintain correct psi with a boost leak will fail earlier.
If Mazda was able to design a simpler and more reliable single turbo setup there's no reason it would decrease reliability.
Having said that, my money is on a supercharger.

my money is on NOTHING. Mazdaspeed RX-8 is already out and has been for a while in Japan, and i HIGHLY doubt they are going to develop a 1.6l engine, risk a turbo(which is going to be REALLY emmissions vulnerable) or put a supercharger on it which adds engine wear JUST for the USA. Basically i think they're gonna do all of the bolt ons and doo dads offered in the MS accesory line. If they do add forced induction, i would say s/c is the most likely route...but still i dont think its gonna happen. and as for the rx7, i doubt that will happen too because it doesn't make sense for mazda to release thar car in the near future as it will just edge out the rx8. most people are either going to go for the sports car or the bread n butter car, and since mazda, like every other car manufacturer hires people that understand car sales trends, will note that the rx8 will have a small market if they were to release a 2 seat sports car RX-7.
and i can't afford a new one.

I would say after 10 years of producing the FD they know the problems and can prevent them. The sequential turbo system was a means to have fast spool up and good low end power without choking the high end. Mazda turbo cars usually have this fast spool characteristic and Mazda also likes to come up with innovative technology (1.8L V6 in the MX-3, Miller Cycle engine in the millenia, sequential turbos in the FD and 20B Cosmos, Hydrogen RX-8, etc) so I'm betting (hoping) on the electrically assisted turbo...

This is getting way off topic, but you can track a basically stock rx-7 without cooling problems. Especially if you seal off the radiator area. I agree that a heavily modded car could have cooling problems, especially if it has a FMIC blocking the radiator.
Back to the point, I agree that Mazda has learned their lessons from the 7 and won't shy away from turbocharging. They do have to do something though with the mazdaspeed 6 coming out with more power and awd, why would somebody buy an underpowered awkward looking (in my opinion) semi-4 door sports car with so many better options (at least on paper) from even their own lineup?

Here's my guesses, from what I've read, and the rumors at the dealership (I sold Mazdas and Nissans to help pay for lawschool - the skills of a sleazy car salesmen translate well to that of a shuyster lawyer).
Anyways
The 3 rotor 1.6L engine is rumored to be in the new RX-7 - its supposed to be based on the 8's platform, but shorter, lighter, and with a more aggressive suspension, and obviously, the bigger engine - they're shooting for 300 horsepower, NA.
The Mazdaspeed 8 that they've been toying with around Mazda's skunkworks in California has that big hot hoodscoop and seems to be supercharged - this is contrary to what Mazdaspeed has done with the Protege, Miata, and 6 - given them turbos. I would expect a very small turbo or a middle-of-the-road supercharger that's centrifugal instead of roots (amplifies the powercurve instead of instant power all the time) because Mazdaspeed likes to preserve the characteristics of the vehicle.
