The guesstimate I proposed doesn't imply a linear demand curve, it approximates base demand as a function of sales over time (Linear) and assumes the success of the price drop (sales gain/demand incease) increases (exponential) as the overall price drops.

At most we have two data-points ($350 and $300 for Wii U Deluxe.) Any "meaningful" extrapolation must be linear. If you are going to use exponential growth how would you accurately determine the growth rate from only two data points? We have the initial conditions (50k for XBO at $500 and 30k for Wii U at $350.) Then we have two more data points for XBO (@$400 and @$350) and one for Wii U (@$300.) I mean there really is no way to predict how a price cut from $300 -> $250 will affect the Wii U based off its previous price-cut and the XBO based off its previous price-cuts. The data is just too little to create a useful trend. It would be easier to predict the value price of targetted demographics, but that is also extremely hard.

Yes yes, I agree with what your saying. But I'm also pulling data from correlations, which we do have, not the price drops themselves, but the overall performance on the market and the duration of that performance. In essence I am extrapolating from those correlations, which I admit is terribly crude, but given the lack of data the alternative "correct" approximations can't be made.
I'm assuming a lot of things to make up for it, and since this is a worst case estimate, I figure I have some leeway here.
I wouldn't go as far as to say I making up things, but since I am assuming things based off of tangential correlations, its a stretch
