I foresee a day when having a .com at the end of your domain will be considered tacky, much like the old marquee and blink html tags of old. Its a no brainer when you can deliver the same message through a domain name and have it be 3 characters less and look much cleaner and less archaic! The only thing keeping .com and .net going strong is the fact that new tlds just aren't fully established yet. Much like when many designers of the past were somewhat reluctant to convert their nested tables over to css and div tags, I feel some domainers are reluctant to concede to the fact that the future changes every niche... Well were looking at this damn future right now!
The problem with that analogy Grego not that there is not some truth to it, but design techniques are different. They are done in different ways, sometimes have a difference of quality or appearance depending on device, browser, etc...
A domain name works the same, Grego.com - Grego.xyz - Grego.Ninja. So now we have to look at the fact that businesses did not want new gtlds, and the public didn't know about them and still doesn't to a large degree.
Creative individuals will make some cool sites with new gtlds, I have no doubt, some start ups may even choose them. But value for a domain investor may not increase.
If there is no liquidity, then what are you doing ? No wholesale market to dump a few off and renew your best etc...
I am not anti new gtld, some make great sense intuitively, but most times when you find those names, they are restricted or premium priced, so I may think a name makes a lot of sense, it is intuitive, but for $3,000 a year or $6,000 that goes out the window. In all honesty how many can a domain investor own at $1,000 a year ?
When Donuts had the one letter names in the first few strings, people loved them, but I know some people who got them, no interest for a year and are not going to pay $260 to renew.
ICANN model different than the registry model, which differs from the registrar model, which all have a better model than the domain investor model.
