If they do it, I don't know why anyone would expect it to happen at any time other than right before the levels get increased, exactly as it's happened in the past. I don't see it as a cash grab. To me, it's a nice way to let players who don't have maxed out artifacts catch up. If you're a player who has 6 maxed out artifacts right now, double weekends are not your thing. If your artifacts are at 80 or 120, then double weekends are a really nice thing when they happen.
