.com is king and will always be. You can speculate about the future all day long, but if you follow domain trends you will like what you see for many TLD's, but .com is still well ahead of the pack.
I appreciate this but my point is that it often seems that if the domain tastywidgets.com has been taken there are so many other variations that are almost as good, e.g. tasty-widgets, tastywidgetsUK, UKtastywidgets, tastywidgetinfo, tastywidgets4u, etc, etc.
