So often in the gadget business, you know something without actually “knowing.” For example, we’ve known Windows Mobile 7 was coming for quite a while, though it is only now being confirmed. Likewise, Microsoft CEO Steve Ballmer making some noise at Mobile World Congress in regards to Windows Phone (potentially Windows Mobile 7) was mentioned in passing at CES (and a couple other times since then); but now it’s officially official.

According to Microsoft’s News Center, Steve Ballmer will be hosting a press conference to discuss Windows Phone at MWC. Slated for Feb. 15 -- that's next Monday -- the press conference will be streaming live and viewable from Microsoft’s Windows Phone page. After the conclusion of the press conference, an on demand version will be made available.

With as rampant as the speculation has become over WM7 and what it will or will not include, we’re not going to read much into the fact that this is only a press conference instead of a full-blown keynote. We’ll be there Monday to watch it go down.
