The main problem with how Munch's Oddysee was handled that a lot of information was released. Therefore when the game was finally released on the Xbox, a lot of people were like "oh this isn't included" and "how come this was shown to us, but now it's changed". And they had certain expectations of the game and then for whatever reason were dissapointed that the final game did not meet these expectations they had.
Therefore with the next game, they are keeping everything top secret. Even when myself and Pilot visited the studios earlier this year we were shown nothing of the new game. On our previous visits we were shown information on Munch, but this time around it was all very much under wraps. But the impression we were given was due to the reasons I've mentioned above that this is why they have chosen to take this stance this time around.
And anyway, we will all be pleasantly surprised when we do begin to see information I am sure!
