What was announced

What it means for players
The official wording answers the format question, but it does not confirm exact map size, seamless transitions, or unrestricted access from the beginning.
This update narrows one specific player question using the publisher’s wording. It does not turn unreleased footage or marketing copy into invented routes, values, schedules, or performance claims.
What remains unconfirmed
World size, loading boundaries, progression gates, fast travel, and map completion tools remain unknown.
