Could be that they are simply waiting to see how things go at Sebring. Its a brand new car and if they run into a bunch of new car gremlins I think LM will be off the cards, but who knows, if it goes like a bat outta hell and runs trouble free...Sarthe here we come!

I think Dyson had an auto entry that was knocked back to the ACO, if thats the case then I think we are safe in saying they won't be there.
The problem with this time of year is that teams are promising alot but cannot back it up, some are awaiting on cars to be built, like rollcentre's radical's or some money to come forward.
As the first race for the LMEs is after the full line up is anounced, the ACO's has no way of knowing how good a new car is going to be if its not at Sebring.
