Having the cinematic and feature trailer at blizzcon is the new norm.
Just read this further down in that thread about the alleged cinematic (I capped it):
I really hope it's not (just) Sylvanas or another used character from the previous cinematics. I hope we get more than Bolvar. (e.g. I personally would like to see a CGI Bwondsamdi, he still is chilling at the gates of ICC).
Makes me think, who would you guys like to see in CGI in the opening cinematic or potential future cinematics (if they continue those)?
