Well, I think this article can be categorized as journalistic filler. No real changes are proposed for MotoGP. Oxley basically just says that SBK should avoid stepping on GP's toes and switch to baggers, adv's and nakeds. Difficult to take this article seriously, though I suppose everyone reacts differently to the reality that motorcycle racing is outrunning the tracks.
My personal vision for the future would be much different than Oxley's. Grand Prix has a recent history of tightly regulated formulas based upon engine displacements that inevitably lead to a standard layout. The 80s and 90s for instance featured 500cc V4 engines. In my opinion, all GP classes should be 4-cylinder because those engines will probably soon fall afoul of regulators. Maybe do something like 800cc, 600cc, 400cc with the current supersport bikes providing the backbone of a 600cc Moto2 class. I guess Kawasaki would have the run off the Moto3 class.
Superbike needs to convert to Next Gen rules, not only to differentiate the series, but also because the regulatory environment for emissions is unstable, and the series cannot maintain the appearance of road-going motorcycles, if the competition bikes continue to fall afoul of emissions regulations. The 600s were the canary in the coal mine, and the 1000s might not be far behind. The superbike paddock also needs to reduce peak engine power to take pressure off of the national series and promote privateer engagement (sales). Reducing the power output could also allow the world championship to return to vital circuits like Monza, Brand Hatch, Laguna, and perhaps a few others. Nakeds could be part of WSBK, but it definitely can't carry the show.
