I think that the only series to do justice to the amount of hype is Nanoha. The problem with my argument is, companies usually overhype.

The released hints are far too vague to interpret. Someone at AoD forums [link gone stale] made an observation that the deleted text of the second hint might be more revealing, and that's why it was deleted. It read (deleted part in italic): "This one will be a bit longer. The paperwork is now on my desk! This one that goes here will make people heads explode. That would be messy!". I don't remember many exploding heads after Elfen Lied, so I guess the text was deleted because of possible implications between "mess" and the licensing process, not the content of the show.

P.S. My head might explode if Mahoraba were licensed, but I'm not holding my breath. The series which missed the boat are usually licensed by bottom feeders, not matter how popular, and TRSI is not one. Case in point, the license of Yawarra by AnimeEigo. Yawarra ran together with Ranma and had better rankings. I personally know people who thought that it was better series than Ranma. Nonetheless, it wasn't licensed by ADV; not even by MediaBlasters.

UPDATE: It was Maria-sama ga Miteru under the name "Maria Watches Over Us". See also, Cutest Cosplayers Ever.

UPDATE 2: I forgot to mention, TRSI licensed 3 seasons (2 TV and the OVA), but apparently 4th season was announced.

LATER UPDATE: Since the forums moved, here's the list of hints:

• It's "coming soon!" It's a done deal. All will be revealed. Who will be happy?
• This one will be a bit longer. The paperwork is now on my desk! [Author: this where exploding heads were added.]
• This one I have a draft on now. Drafts are good, but they are not final enough.
• And if this last thing goes through, everyone will cheer.

To be continued.
