Destiny ISN'T beloved by gamers as a whole, just because of this.
Meh, saying that the main landscape has changed isn't going to offend people who aren't diehard PC players, for people that dabble in all platforms (like me) I might disagree with him but not hate Destiny and Bungie as a whole for that... No where near as intrusive and alienating as Microsoft's' changing stances about online-only consoles and the flip-flopping about Kinect, or EA's rushed development and multiplayer codes. Saying that mouse/keyboard isn't the future is a thing that some people will disagree with but a lot of gamers will agree with.
I expect some backlash, but the game is already fundamentally/conceptually solid (and I found the alpha/beta fun) and it will sell a LOT of copies.
