Hey, folks, waiting for 6th season, huh?
Nope, not really, I've read the books.
6th season will probably be the rest of the plots from the same book that season 5th was (cause they managed to cram like 1/3rd in there - lots of stuff was left out).
The books are good yes. George Martin writes well and has nice ideas. I especially liked his novel Tuf Voyaging.
Thing is George Martin also wouldn't be himself if he didn't multiply plots ad infinitum without closing the bajilion ones he already wrote. You will most likely like first few books. Personally I had enough of his mannerism around 4th. And the current last one - shoot me now. Way too much of everything - more and more plots running parallely, nothing gets explained ever, nothing comes to conclusion. Also the last one was much harder to read, as it was so huge he decided to sort everything geographically, not chronologically, so you have to piece together the timeline by yourself while drowning in multitude of plots and characters.
Season 5 is around that time in books that I became disinterested, so I kinda know I have not much to look forward to
