Its because of May sweeps. The more viewers ABC get during the sweeps determines the amount of money they can sell Prime Time ad's for or something so they need more viewers during May. The last lot of Lost Episodes will air over May.
Told you I didn't know how true it was

As for following the plot with Lost, I'm still fully aware of what is going on - but I can't predict what is going to happen (or even speculate anything close to accurately) like I could in previous seasons!
