Just because the 250 didnt get FI doesnt mean the 450 wont...in fact there is a pretty good thread over in the 450 forum that indicated the 450 will have FI.
As for the WR and what it will look like, I would be willing to be it looks like this (with BNG (maybe)):
Yeah, thats my point, I highly doubt the WR will see it this year, even if the YZ450 does. Wait and see I guess. The 2010 lineup should be announced shortly.
