I like this update. I was actually thinking the other week, "How am I going to find enough time to play to find all of these damn secrets." Well, now it should be pretty easy to move from one challenge to the next.
The hammers are a nice touch, too. I'm sure there will be quite a few challenges I won't be able to complete.
My End of 2008 Hardware Predictions (console only):
Wii : 50 million
360: 28 million
PS3: 24 million
These predictions were made on January 3rd and won't be revised
