On a less scientific, more opinionated point:
I think BTC will, in about March, finally break the $1,000-1,200 barrier. It will make a few big fluctuations, and by the end of the year it will be holding steady somewhere between 1,500-2000.
Unless, of course, China decides to lay of on their rules and declare BTC at least a private currency. In which China will probably start to drive the price higher, and investors will start buying like crazy to try and get in "before the boom" then the price could see 5 figures before year end...IMO
China doesn't need to change their rules as they can just use offshore jurisdictions like Singapore and Hong Kong to get their Bitcoin. If they need it locally localbitcoins will do. Of course, the offshore jurisdictions are more accessible to HNWI than to masses of young geeks and hobby speculators - but they are savvy enough to do the whole voucher-btcchina trick.
The Chinese are smart enough to realize that mass Bitcoin adoption is a fait accompli, and so is people all over the world. There is nothing that can stop it, and the faster people realize that the faster it will grow. I'm getting more cheap coins so that I can join the next 100x growth in 1-2 years.
Of course when that happens the question is what to do with that wealth.
