I approve of this.
With the recent release of Windows 8, we see an enormous shift in the OS-market, and the views of people on OS’s.
The only reason I use my Windows 7 is because of Guild Wars 2, and some other games. But when Guild Wars 2 will be ported to Linux, I’ll be more than happy to format my Windows 7 partition.
I really, really think that porting Guild Wars 2 to Linux will be good. Not only for the community, but also for ArenaNet as a progressive gaming company.
