Personally I was torn weather or not to watch this, I'm pleased I did as it didn't give away to much and considering I haven't seen the second, third or fourth season yet I don't want to spoil anything. Season 5 of Breaking Bad will be the last with sixteen episodes and will be split in two with the first half airing this year before being followed in 2013 with the remainder of the episodes. One good thing there for me is that I have plenty time to catch up with box sets.
I have the official Breaking Bad season 5 Trailer here for you too, you can check that out in the video below. This one, I haven't watched as I think the length of it is bound to spoil something that I don't want to know about, check it out.
