That Ronax thing is sweet, never heard of it. It sounds cool, but then I saw the price tag ($136,460). One day I would love to find a moto GP bike like an rs250, rgv250 or ns250 but no way i can even think about something like that now.
Beta's are sweet too. I'm in NJ, and they are extremely picky about titling and plating enduro motorcycles. The new KTM EXC's can't get a plate here since they put 'for offroad use only' on the MSO, but the Beta can! I've mentioned Beta's to a friend so often he almost accused me of being a salesman for the local dealership.
I agree with the can't make the switch to a 4 stroke thing, a broad power band just isn't exciting. Just like the saying goes: 2 strokes are crazy, 4 strokes are lazy
At the same time, I don't hate on 4 strokes, they have their purpose. I wouldn't want to see a 2 stroke utility quad or similar. That's just not the type of riding I like to do.
