Sorry, but the answers are NO, NO, and NO! First and foremost, ROKU IS NOT ANDROID! They will never add a web browser because they have no interest in allowing you to watch pirate streams and that's possibly the main reason people want a web browser. There's no need for a file browser - any media player will allow you to browse supported media on a DLNA server or USB drive. And finally, you won't see the Google Play Store because ROKU IS NOT ANDROID!
