Personally, I think "spoiler" complaints don't count at this point (excluding DWD). The books have been out for YEARS.
Now, about the show...
The Red Wedding better be PERFECT, it's one of my favorite parts in the book.
The Hound's 1v1 fight better be awesome.
And they need to stop fucking around with Dany's chapters. No House of Warlocks for Clash of Kings? Her dragons go "missing"? Retarded. I've been reading ASoIaF for over a decade now, and I'm pretty emotionally invested in the series. I get that they can't fit everything in, but that doesn't mean they need to cut important info so they can squeeze another sex scene in. This isn't Spartacus, for fuck's sake. I like tits as much as the next guy, but I don't need them to stay interested in the series.
I'M FUCKING HYPED
Seriously, once 2013 hits us, the 3 months leading up to Season 3 will just be a time of preperation for me. My body needs to be ready.
