Even with the downturn, companies are going to have to put their products out there, as it were, in order to register on the buyers consciousness. I'd be surprised if GT1 and 2 manufacturer backed programmes disappeared from LM, after all, the old adage says 'Win on Sunday, Sell on Monday'
Just like continuing to advertise, and to carry out R and D, FI think that the racing programmes, although costly, will continue in some form or other. They may have to be made more accountable, but they aren't just an extra cost that can be dropped without impacting on the sales, a successful racing programe is worth its weight in Gold. Look at Jag in the late 80's, early 90's.
