over a year ago:
It was funny (the father moments), but I don't miss them.
In the narration it was said earlier that something about Hikaru and Tamaki and Haruhi would be the beginning of the end of the Host club. So I'd say yes. The Host club is probably to coming to an end. But I don't know how long until then, so I choose not to worry about it, everything ends eventually.
The only problem I can see in the epic Tamaki vs. Hikaru battle is that Tamaki and Haruhi like each other, so it's not so epic, seeing as Hikaru doesn't have much of a chance.
