From Martin's blog:

For years now fans of my epic fantasy series A Song of Ice & Fire have been writing and emailing me to suggest... ask... beg for the books to be made into a videogame. I'm thrilled to be able to announce that, at long last, those requests are being answered. Cyanide Studios, an independent videogame developer based in Nanterre, France, has acquired an exclusive option to develop Ice & Fire as both an RTS (Real Time Strategy) and RPG videogame for next generation consoles and PC.

Cyanide will begin development immediately, with an eye toward rolling out the games for release in the summer of 2011. "We are all huge fans of 'A Song of Ice and Fire', so it is a true honour for our teams to be entrusted with creating the first video games inspired by this masterpiece" said Patrick Pligersdorffer, Managing Director of Cyanide.

"The twists and turns of the plot will allow us to deliver an experience which can be enjoyed by both long-time fans as well as gamers new to the series. Its rich web of characters, set in a universe where nothing is just black and white, make it an ideal background for both an RTS and an RPG."
