Right now its mostly just speculation based on a very small amount of information. It would be like walking up to the ocean, scooping out a thimble full of water, peering at it then making the announcement "There are no whales in the ocean!"

I guess speculation can be fun, what else will we do for the next month or 6. IMHO I know I have heard of more content to the game than just quests so I am not a worried.
