Coming from a CVG interview with Ubisoft's Theo Sanders...

CVG: How have you been able to utilise the Wii-U's unique features for Ghost Recon Online?

TS: Our focus has been entirely on delivering a great launch on PC. Achieving that has been an all-hands-on-deck effort for the team this year. We're looking forward to seeing what we can do on other platforms like Wii-U once we're on solid ground with the PC launch. So no specific update for now, sorry!
