Email Response Misread as Promise
According to The Hollywood Reporter, an email sent in response to a support ticket about a disc-based version of GTA 6 stated that a physical copy would be available in the following months. The publication claims this language has been misinterpreted by an optimistic internet and does not indicate any actual plans for a physical release.
Insider Claims Rejected by Source

The same insider who previously said GTA 6 would skip a physical launch at release later suggested a disc edition would arrive in December. THR reports that a source with knowledge of the release plans confirmed no such edition is scheduled, either at launch or later.
Context Around Release and Pre-Orders
The clarification arrives during a week that saw GTA 6 pre-orders open with a revealed price and reports of a physical edition containing only a download code. Eurogamer has reached out to Take-Two for further comment on the matter.
