2nd/3rd June
On Tuesday 2nd Jack Tretton will be delivering his keynote speech as part of SCEA's E3 overall show and our colleagues in SCEA will be recording the speech.
As you may be aware, Home does not yet support live video streaming, so they will convert the video once the speech is complete and then make it available for everyone in SCEA and SCEE to view.
So, once its all ready you'll find the speech playing on the main video screen in the Presentation Podium.
Given the editing and conversion process take a little time as does the upload to the servers it will be several hours before the speech is ready. In SCEE we think it will be about 1am on Wednesday morning. However, as an overall experience we thought you would like to see the Presentation Podium used like this. Obviously live streaming is the ultimate goal for this in the future, but in the meantime we hope you find this experiment interesting
