I haven’t watched the video (mostly because I’m having a coffee at a McD’s on my way home) but I think that’s most likely not true.
Why?
Well because of all of the updates and contents GW has pushed out recently, like this last month.
If it gets no updates for a year then yeah, be a little worried.
As for Ash Wastes which I see mentioned above - look, it was very expensive at a time when people are strapped for cash, despite being promoted as almost “Necromunda meets Mad Max” (At least by fans, though GW did hint at it initially) it contained almost no vehicles. I think people were expecting a Speed Freaks style release.
Then after it was brought by some the rules came out publicly and more people were put off.
I just think they bungled the release TBH. It wasn’t what people wanted or expected and had been “nicke and dimed” yet again like the 2017-18 releases. Poor show GW.
