Yeah, this is a good setup for a rotary. Its kinda like the Porsche 918, with its super high revving, tiny racecar V6 that only made power at high RPM, compensated by a electric motor everywhere else... Though I question if Mazda will really be able to keep the curb weight down. Other manufacturers just can't seem to help themselves, and stuff tons if heavy junk in modern cars.

Maybe tuners (or Mazda themself?) will put a centrifugal supercharger on it later. They seem to be en vogue, they are simple and light, and they don't butcher timings/compression and such as much as a turbocharger or other superchargers, with was a major pain point with the RX-8 Wankel.
