Latest rumours have it that you will be clipping a battery to your waist to use it. Very unlike apple, so I’m guessing this really will be the roughest product we have seen from Apple in a long time. Likely a dev kit in all aspects, which is fine tbh. Hopefully they will embrace VR, and games, more than the rumours have been suggesting.
