Personal License - 129.99$ (and I guess that most users use this one) - one time
Education License - 49.99$ monthly or 359.99$ yearly
so... from business point of view it's perfectly logical that Scirra does not care about native exporters. Why bother if bigger money (monthly/yearly) is from education subscriptions? Also making native exporter means more programmers = higher monthly costs = less profit = high risk.
And Ashley is right that at some point HTML5 browsers/wrappers will be good enough. So people can wait months/years
