George R.R. Martin has been hinting that he has "big news" for quite some time now and confirms it's a story recently released by Variety: A Song of Ice and Fire HBO series. David Benioff (Troy) and D.B. Weiss (Halo) will be producing it and according to the article, they're thinking of shooting it in either Europe or New Zealand.
While many of Martin's fans know him today for his work in his epic series A Song of Ice and Fire or his super-hero fiction Wild Cards, Martin has done work for TV before, namely The New Twilight Zone and Beauty and the Beast (yes, the one with Ron Perlman as Vincent and Linda Hamilton as Catherine). Martin will be co-exec producing his series along with others.
Interestingly enough, the article states that A Song of Ice and Fire is a seven book cycle and that the target date for all of it to be finished is 2011. Of course using Murphy's Law, I predict it'll actually finish in book eight (it's an even number), and will be done by 2018 (adding one year delay for each book plus two extra years for the 8th book).
