Microsoft's VP of Xbox Games Marketing Aaron Greenberg has confirmed that the upcoming Xbox Games Showcase will feature no CG trailers for first party titles.
The Xbox Games Showcase takes place at the end of the week, promising roughly two hours of upcoming Xbox titles as well as an extended look at Starfield – the next big RPG from Bethesda. Ahead of the show later in the week, the VP of Xbox Games Marketing Aaron Greenberg has announced on Twitter that the upcoming show will not feature any "full CG trailers" for first party titles, and that everything will be "in-game footage, in-engine footage, or in-game footage with some cinematics".
All trailer will be labelled appropriately so it's 'clear to fans'. However, this doesn't completely rule out CGI trailers for the show as Greenberg specifically mentions first party titles, and that first-party won't be "full" CGI trailers.
