Hey! JAW had a live stream of MOHD running earlier today, announced through facebook. Haven't seen anyone mention it here so far! Enjoy about an hour of Munch (note: gameplay begins at 0:35:00 roughly):

It has a nice commentary from Stuart, though it's a little hard to hear over the game at times. He mentions the things that have been improved and answers some questions from fans.
They removed the boing sound from Munch, and replaced it with a more accurate 'frog flipper' sound. It's definitely better, but in my opinion perhaps a bit too loud- maybe there'll be a way to lower the FX volume?
