Yep, Sherco was (supposedly) ready 18 months ago with their FI 2-strokes. I have not heard much out of the Beta camp, but I don't expect them to be caught with their pants down.
Not sure what the story from Yamaha will be. Will they continue to offer the YZ125/250/250X as a simple and cheap alternative to the technology leading Euro bikes, or join the party? In a year or two, the YZ250X, if left unchanged, could be $3000+ cheaper than the Euro bikes.
