Well, it's BBC, you never know if a new season is really approved or not until it starts happening, and it's not like Martin or Benedict don't have other stuff going on, so even though as it stands now there will be a third season, it might still change any day/month/year. I mean, this season was supposed to happen last year and they dragged it out till now.
But I'm actually still kinda hoping Sherlock does appear at the end of the episode and we know he's alive and well, but, who the hell knows anything until I watch it and am broken and tumblr needs to stfu.

Eh, what can you expect.

DAMN FUTURE! CANADA BETTER TREAT US LIKE ... KINGS.
