First off, Take-Two CEO Strauss Zelnick has confirmed that the publisher's sales are mostly digital, in response to Sony's controversial decision to stop manufacturing physical disc-based games. Sega has chimed in, also, noting "a digital shift is crucial" for the longevity and health of the games industry. "This is all net revenue, which includes DLC / microtransactions, [of course]. "Global excitement for the launch of Grand Theft Auto Six continues to build, with the title having an exceptional start to pre-orders," Zelnick said in a call with analysts. Despite the apparent strength of this earnings call, Take-Two stock opened down 1.9 percent this morning, coming in at $228.2 a share.
