Several of the most interesting TLD for the future are listed here ( .ESTATE / .SOLAR / .SYSTEMS. / .FARM etc.) We predict that in a few years (maybe sooner) a lot of the new TLDs will go sky high, and compete with the .COMs. Why will probably many say ? The answer is simply. Many of the new TLDs are quite simply better (and more correct) than the .COMs.
And why pay overprice for poor 2-3 word .COM's when perfect TLDs still are available at attractive price levels ?
I've heard people say that the .COMs and .NETs are stucked in people's mind, but that doesn’t mean things will always be the way they are today. Down the road the .COMs will fall out of favor and we’ll see gold domains in each new TLD, and the .COMs will end up as one of many.
