i would have liked to participate personally but unfortunately i will not be able to be there, i really hope that there will be a live broadcast of the event or a recording to see...
I agree it would be nice to see their presentation live, but i doubt there will be a broadcast but i am sure they will make some videos for their promotion, they have perfect opportunity.
They also had a recording of their recent presentation in Tel Avis so I guess they will also make a video of the London event and publish it in their youtube channel.
