Here is a quote from the main Bannerlord thread, where this issue has received a lot more discussion earlier in the day than here (why does general Bannerlord stuff even get posted here, like it is an alternative forum rather than a thread for a specific sub topic, aka blog 12?):

Since this was mentioned a few pages back, I'll post a clarification here for you hardcore Bannerlord thread pilgrims. We'll be making our own announcement, later today anyway which will cover this too.
It's not our event, so we don't have control over the production and media they choose to distribute from it. What we'll probably do is just wait and see what comes out from PC Gamer itself and then release our own stuff in support, going into details and covering everything, similar to how we handled it with Gamescom. We of course understand that nobody wants to miss out, don't worry!
I doubt they will simply post the 40 minutes in full, it is a lot to watch at once and many people probably would prefer to get the highlights or have it split into two or three blogs. But Lust says we will be told everything there is to know, and probably get video clips of all the important stuff, and there is no reason to doubt that- as he says, similar to how they handled Gamescom. In any case, we will probably hear stuff from visitors to the event who post online about what they've seen and heard before the Weekender is even over, just like at Gamescom. PC Gamer will doubtless put short highlight videos online in the week following the event and then TaleWorlds will go into detail and show us more of the less spectacular stuff.
