On January 4th, HP invited to join on the morning of February 9 for an "exciting announcement". But it appears that they're now also reaching out to others about another event later that day.
This new invite reads: "HP webOS. The future revealed." Below that, it lists the same February 9 date, but lists the time as being from 7 PM to 9:30 PM. And it'll be in the same venues: Fort Mason Center, Herbst Pavillion in San Francisco.
Speculation has been that webOS 2.0 would be more formally unveiled at that time. But we also now know that tablets will definitely be a part of the day. Because HP EVP Todd Bradley told CNBC that "you and I'll talk about that on the 9th."
So, webOS 2.0, tablets, and probably some new phones in the morning to woo the press.
