I don't think essentially replacing most of Testnet with a specialised 
test chain is a good idea, but this might be a good time to consider a 
4th test network with very large blocks from genesis onwards.

I do tend to think 2 years of 8mb blocks is excessive as a test, too, 
and while certainly large projects should have or can raise funds for 
test infrastructure, I would worry about the smaller stuff out there. Is 
there anything specific 2 years gives us over, say, 6 months?
