I had heard they were going to change the OPT duration to be 14 months.... this is a crappy system.... you are out of luck either way dude!!! your best option is to begin your OPT as late as possible, and go to Nepal for two months in Aug-Sept next year (and be jobless) and come in as H1b again..... you should graduate in december, can you just take 1 class your last semester and push grauduation until december!!! you can do the walk in may if you'd like!!! I doesn't have to be the same semester you graduate!! hope this helps.
