Nobody said that these new extensions wouldn't be used at all. They are being used exactly how they are supposed to be - for disposable throwaway campaigns and promotions.
I think that every gTLD just lends more authority to .COM for branding and 'home base' operations.
Just because I use a smart phone doesn't mean I throw my desktop computer out the window. Most gTLDs are a compliment to your online presence, but should not by your home presence if you are marketing to the masses.
There are a few exceptions, but definitely not the rule. The day a major company switches their main website to a gTLD... that's the day it all changes... but that won't happen because one of the goals of the program was to increase the value of quality .COMs, not trash it.
If XZY is the go-to for these kinds of campaigns, then so be it, but don't ever expect a company to pay big bucks for a .XYZ... and that therein lies why it's more attractive to invest in .COM's.
