exactly what i said would happen happened - the "respectable" exchanges figured out they were starting to hurt themselves, inside the information market.
(you will notice that WDC only got to one or two "major" exchange bter.com etc. did not get on BTC-e where as they took CNC.)
if a new batch of exchanges come out to support new releases , then there will be more instamine "coins" .
but they will be of a lower respect level, not that it matters much anyhow. It is what it is.
I like it, its a beautiful free market of opportunity.
