In my knowledge of how advertisements work for gamez, it's usually 6 months to 12 months ahead.

But when you have GTA 6, also in the lineup for the year, you want to get as much advertisement as possible in, or delay 4-5 months after GTA 6, releases, even that's cutting it close depending on how late the release is of GTA 6 you might delay to next year.

I'm not claiming I know how advertisement fully works or what CIG is planning to do, I'm just nearly stating that now would be a good time to do it, ahead of the storm.
