I've not seen Google doing much hyping, just lots of people excited. To an impartial observer, perhaps overexcited, but that's a far cry from over hyped. The whole project has just been rumours for the past x years, and not even very loud ones. Hardly "hype".

Maybe. We're talking about a brand new product in a domain that has, what, four other major players (at least on Windows). That's a big deal, especially given it's coming from Google.
