Mazda is once again going against the grain, much like that one kid in high-school who mouthed off to all his teachers and peers when he deemed they stepped out of line.
Lately theres been a huge lack of I6's in market that seem worth while, especially with the lack of a Toyota and Nissan I6, rather them opting to reach out to the Germans, or just using the traditional V-layout.
Mazda wants no part in that it seems, as they have confirmed an N/A I6 for future platforms, in particular a longitudinal RWD platform that we could only assume would have a long hood to holster that power train.
Fingers crossed that it resembles the RX-Vision concept from a few years back
Aside from that, the brand is continuing its push towards a more 'luxurious' image, and the next generation will likely be its largest step thus far.
