In a blog post written this Friday, Dan Teasdale, the lead developer of Rock Band 3, announced that he will be leaving Harmonix. In discussing the reasons for his departure, Teasdale stated "I want to be able to help drive the vision and direction of a game, but at the same time be hands on and physically implement and iterate on the low level of making games in a more substantial way than time affords me when working as a lead on multi-hundred person titles".
In order to have his cake and eat it too, Teasdale will be heading to Twisted Pixel, the studio that created XBLA titles such as The Maw and Comic Jumper, to work on "a ridiculously cool new project". Sadly that's all the news we have on that title though.
For fans who are concerned about the upcoming release of Rock Band 3, fear not, as Teasdale stated that the title, which we were quite impressed with at E3 is "now design complete and on the final path to 0 bugs, GM and distribution". So look out for Rock Band 3 when it releases on all 3 major consoles this holiday season.
