The pre-order announcement is the most telling document. It named two editions, two prices,
a bonus pack, a pre-load date and a free month of GTA+. If an online component were being
sold, it is the page it would have been sold on.
Three things would move this out of the blank column, in roughly this order of strength: a
Rockstar post or storefront listing that names a mode; a Take-Two earnings statement giving
a window or a business model, which would put the claim in the same class of document as the
release date; or a platform listing showing online features on the product page, which is
where the absence is currently most visible.
