You could argue that a teaser was not necessary with all the publicity and advertising gained through the existence of this forum.
I would agree with you. You already knew it was coming. It is not a case of a project thought dead where we want to renew interest.
Creating a teaser topic was a requirement, which is the reason why we made it.
An interesting question is why so many do not understand that this is a teaser and/or the purpose of a teaser. Part of it is probably due to the timing. It was posted at a time where a project thread could be expected.
Another more interesting question was whether it worked. Falcon seemed to get annoying which is a good thing. Annoyance is far better than ignorance. Then again, this is Falcon we are talking about, so we should base anything on what he wrote too much.
Questions like "Can they pull it off? Will knights only going to suck? How the hell did they only have knights in the story?" and so on can help keep interest in the game. Naturally only posting knights as characters does not mean that there only will be knights as characters. Who knows? Maybe it's just a stunt.
Teasers can also be used as feelers. Basically feel how the community takes the project. What there opinion of the project is. Teasers are usually posted at a time where relatively big changes still can be made. Pulling a stunt in a teaser may however render the teaser rather invalid as a feeler.
So is this a teaser or a feeler? Or a hybrid?
And finally... Why did I go through the effort to post this analysis?
