Train will remain alive and well until the next official hardware announcement... then we'll all be bitching about not buyiing enough shares under BTC6.
Agreed, we've had several stops on this train ride already:
0.5 XBT/share
0.7 XBT/share
1.2 XBT/share
2.5 XBT/share
4.5 XBT/share
Double digits
will happen in 2013.
Double digits would entail ASICMiner shares making up 30% of all bitcoins ever mined. Do you really believe ASICMiner is worth that much?
Friedcat's franchise plans on top of the hardware selling implies he's planning to grow way beyond 30% of the hashrate share. Do you want to bet against him?

ASICMiner products probably exceed 30% of the hashrate share already. But you have to realize this:
ASICMiner valuation = (ASICMiner hashrate share + ASICMiner customer hashrate share) * mining share of bitcoin valuation * bitcoin valuation
I highly doubt all mining makes up 30% of Bitcoin's industry, let alone a part of mining.
