Lol, how many renderings have we seen of countless proposed Chargers stadiums? These drawings are never final until, as they say, "the fat lady sings".
Final designs must be approved by the DCPC/CivicSD, who quite often ask for modifications to plans (usually in return for more lax development requirements as an exchange).
That said, I really hope they can come with something more bombastic for what is supposedly one of the most valuable real estate parcels on the West Coast.
Just anything but a f**king Ferris wheel.
