Ten new TLDs is still a significant artifical scarcity - it means in 100 years that we will have a mere 1300 TLDs. And that's in a system that we know can readily hold a thousand times more.
They are proposing essentially one TLD new TLD per month - with time off for two months of holidays. But in reality it takes only a few seconds to add a new TLD to a root zone file - faster if one bothers to create a bit of automation. I can hardly see a need for the rest of the time the committee thinks is needed to add a new TLD.
It sounds like the forces of Internet Ossification and stabilty-over-innovation wrapped in words of Uncontradictable Techno-ese have come to roost on the Internet as heavily as it came to roost on the telephone industry of the 1950's.
I'm doing pretty well with my sites, where I go out of my way to avoid using.com addresses (my sites aren't primarily commercial). I've got.info,.org, and.name sites that are getting decent traffic.
