The Rare refugee studio is called Playtronic Games and of course it is in the UK.
From what we have been able to gather Playtronic is hard at work on the spiritual successor to Banjo Kazooie. There are still a lot of unknowns like besides it being released on Steam Early Access, we don't know for which consoles they will be targeting. However, they would like to push for the Wii U if the fans indicate their interest.
Despite an exhaustive examination of their new website, there just isn't much to tell. We wonder if the indie developer will move to a Kickstarter campaign to fund the project or if they will self-fund? Will Playtronic stay Indie or will they be working with some sort of a publishing arrangement that will help fund the project. A lot more questions than answers, we have to wonder when we will hear the plan.
