Quite so, and what people fail to grasp is, at that growth rate, anyone who places an ASIC order for above $20 per GH/s will no longer get a positive ROI. That means all unshipped BFL orders are now worthless. Same with Avalon and it's derivatives. Those units will no longer cover their monthly power costs in many areas.
This also means that the price of BTC/USD has to rise or miners will have to switch off their gear.
Miners need to be lower than 3watts per GH/s to still be viable. BFL, Avalon, and ASICminer are not.
