So there are a lot of economic, timing and psychology factors to take into consideration. It may be, for example (and I've no knowledge if this is the case) that Korg already know quite well how many Kronos they'll sell at each price point they introduce it at. There have been enough generations of keyboards for them to have a good analysis of buying trends. Hence - they may be right now 'counting beans' on this forum and many others and will identify an optimum ratio of units made to unit price; and they'll announce it when they know that. There are probably many other practical considerations - if the units are not made yet and, for example, touch screen prices are fluctuating, they simply might not yet be able to put an exact price out.
So Kronos may not be cheap - it may be quite expensive. Look at V-Piano and CP1 for example - these are both extraordinarily expensive. One would think that Roland would want to sell more V-Pianos and hence make them cheaper - but there must be real reasons we're not privy to but which Roland have analysed very well that's keeping V-Piano so pricy (beyond the very plausible fact that they may simply want to give the Roland brand more panache by releasing ridiculously highly priced keyboards).
There's a possibility that OASYS was never intended to be a big seller - it seems to have been a labour of love rather than a 'next big seller'. Kronos on the other hand seems to be more targeted for mass consumption so that should bode well for the price. But getting back to my original point - almost everyone here is going to buy one no matter how expensive it is - the vast majority here has already made up its mind and Korg know that. How many other people in your life do you know who are as interested in keyboards to join Korgforums? Probably nobody. We're a captive market - we're flies heading into the lamp!!!
