I would be upset. But this year they said (pretty sure it was bashiok on the forums) that this year will have the most diablo3-related information than previous blizzcons. This year is supposed to release a TON of information on D3... According to bashiok that is.
I'd just be really surprised if they didn't release the 5th class based on that info.
