As far as size is concerned, the Alexa 65's 54x25mm 6.5K sensor is the largest and highest-res in motion video, but this camera is a specialty item that's only rented out by Arri, you can't actually buy one even if you had the money for it. Either way, one can't reliably digitize and print film while preserving more than 6-8K of real detail, so you could say the Alexa 65 is already on par with IMAX.
If Arri had managed to squeeze in a 54x40mm sensor, then anamorphic lenses could be used to compress even more detail into the shot, but honestly I think that this is more than enough as 4K as the distribution format will be around for a while, and you're just oversampling at this point.
