I used to worry quite a bit about rumours and they just keep coming, but I learn from them too. Sure the 720p stuff seems to turn out to be true after all, nothing that can't be fixed though. Has been said multiple times now that it has to do with the tools and in time will get better.
As for these people commenting on that blog. I wouldn't take anything seriously about that, cause anyone can make a name like Xbox Dev and claim those games are all running those resolutions, same as all the trolls acting like devs and what not.
