To me, the B looks like it's a dead man anyway... and the recent slew of bad news being leaked, makes me think that delays are imminent (USAF/USN IOC 2020?).
US decisions don't bother me as long as they don't heave the price skyward, F18/Typhoon for the next 13 years seems like an absolute no-brainer to me, especially if it means ploughing money into the Typhoon programme for a few years...
