Meh, that's pretty standard practice due to the Osborn effect. [1] At the Pi1 phase, Rpi was a pretty small company. It wouldn't have been great for them if rumor got spread far and wide that Pi2 was on it's way in a week or two.
I think the criticism of saying "we're not even thinking of a replacement" is fair, the standard dodge "we don't have anything to announce at this time" which is enough to avoid the Osborne Effect.
