This may be right. The abundance of new extensions may have the unintended effect of making the .com more valuable.
But it also has the very real effect of limiting the number of .coms that sell and also wildly extending the Time to Sell.
In the past, a founder wanting to build a new venture would see the value of putting down $2-5k to acquire a matching .com domain name. Now, not so much.
Same founder could buy a relatively popular.whatever and build on it.
Meanwhile, the domainer is stuck holding his .com and paying renewals. Multiply this by several hundreds or even thousands of domain names and the idea of the proliferation of .whatevers making .com more valuable is not so comforting.
Then, there are founders who built on a .whatever who now feels entitled to your .com and would proceed to harass you with a UDRP.
Overall, not a pretty picture.
