If this becomes the final ELMS 2013 calendar, I'm pretty sure that this will share the same fate as the 2012 ELMS did. They'll race at Silverstone (attractive circuit * on same weekend as WEC), they'll probably do Imola, and the rest will be cancelled then due to lack of interest.
Edit: Just read somewhere that they'll do 3h races only. So 15 hours of racing are planned for the whole season. Isn't this called endurance racing any more?
