It is no coincidence that the rumour non-sense started on December 6th, the two week black out period limit. RIM is limited in its ability to respond but I assure you Heinz says what he means. I assume this to be a desperate ploy to allow some followers of the editor out at a decent price or to obtain a quick profit.
BB10 will be released as detailed and no one would coordinate a World Wide launch to allow for a May delivery hehehe. I do enjoy this desperation though. I wrote this down a month ago that this EXACT thing would happen. Since they have a track record of this behaviou the market would shoot first.
A good chance for you to buy in at artificially low levels. I expect this to be shaken off eventually.
