Once again, I wouldn't really expect anything targeted to (or particularly interesting for) any player who has already extensive familiarity with EA. It will probably be another trailer aimed mostly to the casual audience barely aware the game exists.
The previous trailer striked a good balance between both in my opinion. It introduced the plot and the characters while simultaneously show new places, new features (level 5 spells, kobolds, half orc, owlbear wildshape, new body shapes...). It is a trailer, of course they wont show a patch note or a spreadsheet of stats.
