Uh, what? There is absolutely nothing in the Kickstarter information that even mentions Windows Phone. In fact, they explicitly state (emphasis mine):
Further updates only point out that they are hopeful to follow the Windows RT ARM version (which hasn't been completed yet) with a Windows Phone version:
Sure, they hoped that it would be helpful to have the ARM / Windows RT version's code available to help in getting the Windows Phone version out. However, they've said all along that ARM would happen at a later date, and the rest was just optimism. At no point did they guarantee any timeline or make any promises about Windows Phone other than they hoped the more money they raised, the faster they could get it out. And as far as them being paid for this, of course. Except the only thing donators were promised as a definite is the reward tier that they chose: some hoodies, mugs, a banner in the app whenever it is released, etc. And as Kickstarter says themselves in their blog, they are not a store. You are not purchasing a specific product. You are supporting a group/company in making a product. Sometimes, those products don't get released at all:
Again, I get that people donated money and want VLC to happen already. I want VLC to be released as well (and actually donated a few bucks as well). But Kickstarter support doesn't guarantee a product will actually be released, and it definitely doesn't guarantee it's timely. Feel free to be impatient about the VLC release, and feel free to keep waiting for it. It sounds like they're finally very close to a beta release. That being said, if you do wait, you only hurt yourself. Moliplayer Pro and CCplayer are both very good (and inexpensive) in the meantime, and with those you don't have to hold up your own enjoyment of your device for something that isn't ready yet. I couldn't imagine waiting two years for a function I need when there is a good alternative for $3.
