I don't think "registrars" have anything to do with the creation of this "innovative" domain. The creaters of this domain include the likes of Microsoft, Vodafone, T-mobile, Nokia and Google...yes BIG G too....no reasonable person would imagine any of these industry giants giving a crap about milking us...the domain speculators....they're all in this together and the real "speculation" is that they are onto something that's likely to be really Big....but as to exactly what and how...we really don't know yet. Many have reasonable ideas but no one knows for sure as to how these big players intend to leverage this new domain that they have created. Each one of these companies are worth in billions with a solid track record...they are not stupid....IMO, wise are those who observe these things keenly and act on them in a timely fashion rather than having deja vu of 90's (for .coms) and 2001/02 (for .infos & .us) all over again in 4-5 years. I was not there for .coms but I've NEVER regretted taking part in landrushes and early regs (first few days of open registrations) for the newer extensions that I participated in such as .info, .biz, .us, and .in. The kind of names one can get in these early days would be a dream in just few short weeks, and if one does not attempt to be too innovative in name selection, you can almost always get your money back plus some for these names down the road.
Just my $0.02 based on 6+ years of domaining. Take it or leave it...Cheers.
