My GUESS is that the London meeting was a dry run for the US east coast and west coast meetings. It let them see how their presentation floats before they do the key ones in the USA. Allows them to collect some of the intel and questions they may have for their next meetings.

Next week (reaction to this video intel) and early April (milestones and partners and hopeully NRE) should be very interesting as well as June (NASDQ)
