Notch (Mojang) , Gabe Newell (Valve Corporation), and Rob Pardo (Blizzard) have all publicly expressed concern about the direction Microsoft is taking Windows 8. Windows 8 will have a ‘metro’ mode which won’t be an open platform.
There is much confusion over the issue which is normal. But there are too many people saying ‘nothing is going on here’. These are the most high profile people involved in PC gaming. It smells like Microsoft’s viral marketers are working overtime for the damage control. Windows 8 is to be the pot slowly warming and, I assume, Windows 9 will be the pot boiling.
These guys have nothing to gain by speaking out against the OS. They wouldn’t be doing it without a reason.
