The satire/imagery in the trailer hit pretty close as an exaggerated, absurdist view of modern day social media culture. I'll reserve full judgment until we have further info, but it appears they're not missing the mark as badly as I first expected.
On every other front though, it just looks like more GTA. Fine I guess, but unless they improve the mission design or the narrative is actually engaging this time, I don't see the fuss (beyond "yeah but it's GTA, man!!!"). RDR2's story did a lot of heavy lifting covering for that game's shortcomings, and it remains to be seen if they can repeat that trick after losing a lot of their most high-profile talent.
