It's definitely big news for fans of the show, but it's 2014, everything is in HD.
Anyway, I think it'll give the show a fresh perspective though. It will feel brand new. I wonder if they'll re-do parts of the house since they had to replace cameras anyway.
Which is why the last show on the planet in SD entering the world of HD is such a big deal!
I hope they give them at least one extra room to escape to :s
I started watching the show last season and it bugged me so much how it was SD.
