How many new TLDs have been added since .com was spawned? and how many of them have any real worth or value?
No-one who isn't either away in investment capital or is a multinational is going to be able to afford to run a vTLD (v for vanity, naturally). Everyone else is still going to want a .com, with .cctld and .co.cctld rather less popular. This whole exercise solves nothing but an ICANN budget shortfall and benefits no-one else.
