Green light for Game of Thrones?!

Ok this is getting quite confusing... it's not official yet, but here's the latest news from the Winter Is Coming blog, which reports a comment from someone stating that HBO has unofficially given the pilot the greenlight and is actually preparing for filming the other episodes: 

I can confirm without revealing sources, that the pilot has been given the green light, due to HBO activities in Belfast, booking items and services for the next several years. Services that tie in with the set construction(s), they have been asked for a quote for the next year, invoice has been sent, payment has been made. It is happening folks, and it is killing me that I cannot tell you how I know this and what I have seen. I promise, as soon as they announce, I’ll spill. But they are taking their time doing it, I know they have already approved the pilot, and are already getting things in motion for a first season shoot!

And also HBO on Twitter replied to a fan asking about GoT saying this: 

No news yet on Game of Thrones. As soon as there’s official word it will be announced here and on Facebook. Promise. 

And Winter is Coming notes how they say "as soon as" not "if" as if it was just a matter of time... well this is great news after what we had heard just a couple of days ago!! Let's hope all this turns out to be true... still it's a bit early to celebrate maybe :P
