Upload & Sell: Off
Fujifilm kept retail prices on the X100 high for some time, and due to what was probably artificial supply constraints in some market areas, resale prices for the camera were kept high for quite a while too. Thanks to what was then still high demand and short supply I sold my X100 for $100 less than I paid for it new, after using it extensively for a number of months.
Could that experience translate to the RX1? Maybe, maybe not. At more than double the cost of the X100 intro price (in my market), the RX1 certainly appeals to a smaller pool of potential buyers.
Then again if Sony produces and/or makes available enough only to keep supply tight, prices will be maintained.
In the early days my expectation is that supply won't be sufficient to meet demand at least in the larger urban centres my assumption is that I'd be able to resell the camera for more or less what I pay for it if on handling it I have a sudden epiphany and realize I've been kidding myself.
Going out on a limb, it wouldn't surprise me if some sell RX1s for more than list in the early days assuming supply is, or at least feels, constrained.
