Rare is working on a new Battletoads (maybe just the Rare name though like at the Killer Instinct reveal trailer, game could also co-developed by another studio)
Anniversary update will gets its own landing page on Xbox.com with the major features listed, prob "available now" at E3 for preview
Based on the hundreds of lines of source code these are most logical things I could catch within the past few days. There is so much more, but it's really difficult for me to determine what is still relevant, what is just old data and so on. I also see many Conker tags and connections, but I can't find anything concrete about it. So this could mean nothing. I only wrote down the things that will most likely be accurate and are based on recent data updates.
That's all I have for now. Nothing on hardware, sry.
