Excellent news for sure, if true, and Star Wars News Net has a history of being reliable with leaks. The GoT producers/writers are perfect for exploring the Old Republic era. It is also really nice to hear that Disney wants to open up the universe a bit more with a more mature take on Star Wars. Hope we are actually looking at an R rated Star Wars movie here, as Disney is becoming more an more open to allowing R rated movies in recent years, with Disney saying they were open to future R rated Deadpool movies, and rumors of an R rated Blade movie by Disney.
Wow...you sure like R Rated movies. Haha. Don't get your hopes up for a similar take on Star Wars. Most of the R elements in Game of Thrones are because that's the way George R. Martin wrote them. But who knows, maybe you'll get your wish. If it serves the plot I might be okay with that decision, but if it's just for shock value I'd rather they stay PG-13.
