If they announced HL3 in a similar way to Kaiten it would be kino.

>the collective sigh of disappointment that a sequel to rebellion is never coming
>suddenly the lights cut out
>a trailer starts playing out of nowhere
>OH FUCK IT'S HAPPENING

The way they dropped it was fucking kino, everyone was done at that point ready to fucking leave and they dropped it then it was perfect. If they did the same with HL3 it would be amazing.
