Yeah, it's quite literally just the first trailer, but they've already got people confused. This appears to be a reboot, but since they're using the major twist from the end of the last game, it definitely muddles things.
And in AK, you end up taking Freeze's wife out of the freezer, and they dip.
That's what makes me certain this is a full (unnecessarily confusing) reboot. The last game really left the cupboards bare for a sequel in the same storyline that wouldn't come off as being made just because.
I'd say from the tiny bit they've shown and said so far, this might not be a GaaS game but it definitely has gear. There's not much need for damage numbers and the like if stuff like gear and skill trees didn't effect those numbers.
However, I won't be surprised in the least bit to read some point down the line that this originally was supposed to be a GaaS type game, and when WB figured out that this and Suicide Squad were coming out close to each other, they told them to cut that shyt out, and we got what we're seeing now.
That said, as someone who's played Destiny since nearly the beginning, I'm REALLY hesitant to have another game like that in the rotation, because no matter what, they almost always fail to respect the player's time. As I get older, and my life changes, I really don't have the time or patience to run the same missions multiple times in the hopes of getting the right roll of a weapon, or grind out currency for stuff. But to be fair, this game type is in its relative infancy, and could change over time.
