If you're really looking forward to Valkyria Revolution and don't feel like waiting until the western release during the first quarter of next year, you now have a chance to try it out right away. A demo of the game has been released in Japan for PlayStation 4 and PS Vita (the game itself will also be released on Xbox One) and can be downloaded right away.
The only catch is that you need a Japanese PSN account, but those are easy and free to create. If you are unsure how to do this, it's helpfully explained over on Reddit.
