This has me very excited! If the new SkyActiv-X engine can output more than 200 lb-ft of torque while keeping fuel economy in check or improving upon it, that will be amazing. Pair that with some weight reduction and I don't think you will need a Mazdaspeed model.Official announcement by Mazda Australia with some details:

It is also mentioned that a supercharger will be used with the new engine. This means bigger potential gains from the aftermarket tuners.
