Just an anecdote, I went down to the local shopping centre tonight. As I was going in, I heard a kid talking to his mum about the film (they'd just seen it). When I was queueing for McDs, there were another couple of kids talking to their mum again. They were all SO HYPED. The last time I remember overhearing just random people talking about Sonic was when X was still being broadcast, and they were nowhere near as excited as this.
