Synchronise the scripts, make sure the English presenter can keep to the same pace as Yoshida, and a live simultaneous English keynote should be quite doable without having to hold up the actual speech to provide piece-by-piece translation for a secondary audience.
For that matter, I think that should be done with the Live Letters as well, although perhaps they don't want to have a permanent "English counterpart" to Yoshida who steals all his glory in the English side of the fandom.
"Live" subtitles could be another possibility for a planned presentation - obviously not able to convey every spontaneous remark in the live presentation, but the actual information content could be prepared ahead of time, and overlaid on the video at the appropriate time. Would be a bit like a PowerPoint presentation (though a more intense job for the computer operator) and able to give the extra degree of detail that isn't usually written on the slides.
