Facebook has something in the oven, and we'll find out what it is next week
Facebook is holding some sort of Android related event next Thursday in Menlo Park and has sent out a slew of press invites. Nobody is sure exactly what they have in store, but speculation runs from a better (working) Android application to the rumored HTC Myst Facebook phone.
There's also rumor of a "deeply integrated" Facebook experience built into the devices people will want to buy. Zuckerberg has been pretty adamant that building a phone is the wrong way to go, so this is certainly a possibility. We're not sure exactly what to expect, but we know Facebook does things in grand style. We'll know more next week.
