Not in the near future. The reason we released a CoronaCards version for WP8 is because we currently only support a subset of features compared to Corona Simulator built apps. The features we do support for WP8 is at about the same level as it is for CoronaCards for Android/iOS (ie: no support for native UI, in-app purchase, ads, notifications, etc.). But most of the features that are missing can be implemented on the native side via our Lua/.NET Bridge, making a CoronaCards-like solution the best option at the moment. And since CoronaCards is your only option for WP8, we thought the reasonable thing to do was to make it freely available to Pro and Enterprise subscribers. This seems like the most reasonable compromise at the moment. Especially for those Corona developers who want to take advantage of Microsoft’s incentive programs to port their apps to the Windows App Store, of which their is a time limit.
But that said, even if we did add WP8 support to the Corona Simulator, you would still need a Windows machine to do the final app signing via Microsoft’s developer tools. Meaning you would still need a Windows OS license. So, why not give WP8 CoronaCards a chance? You can get Microsoft’s Express version of Visual Studio for free and we offer WP8 CoronaCards at an unlimited trial basis. And I’m proud to say that our CoronaCards integration with Visual Studio is far simpler to set up compared to what we have on Android and iOS. We worked really hard to make it as easy as possible.
