Kobo have a number of interviews next week, and according to my sources the interviews will be under an embargo. The journalists won't be able to talk about news discussed in the interview until Kobo give them the green light.
I wonder what they're keeping secret? I don't think it's a new app; apps aren't that important.
I have one improbably theory I'd like to toss at you; Apple could buy Kobo. I know it's crazy, but stranger things have happened.
My guess is that the embargoed news will probably cover Kobo's new ereader. I've gotten a number of back channel hints that they're working on one, and that it might be a tablet. but that's just a guess; we won't know for sure until after the embargo ends.
P.S. The picture at right isn't the new Kobo ereader; it's an Android tablet that. At least, it's probably not the new gadget. (I don't know.)
