I think the urge to cash out before that point will take a lot of people over.
That's not the only issue... there needs to be a LOT more buyers because most people wont be buying whole BTC at that point.
Nowadays a typical first buy is in the region of 50 BTC. At $9000 that person can only buy 0.5 BTC...
Basically, the user base needs to continue exploding for this to have any chance of happening, and it won't any time soon because Bitcoin is not widespread enough yet.
The user base is exploding there is a queue of 9000 at MTGOX
and when i gets to 1000, people will my mBits
so they still get a whole mBit
and can watch their mBit become 10 x more valuable
rinse repeat
until uBit = $1USD
Then its usable currency
