Spiffy, it is great to have conservatives as well.
5 dollars by Jan 2015 is quite conservative guess - it means it will loose even to BTC which I do not believe in.
WDC has higher growth rate than BTC. BTC is quite soon mainstream but WDC is a project that will definetely take the markets. If LTC has done so much progress, why not WDC (which is much more organized).
After all, there is still very little to do with WDC, only marketing and that's it. It will be official currency.
If the principal in economics holds, good money replaces the bad money the WDC replaces BTC despite the fact that BTC is a good challenger of WDC.
