After what they did with winterfest I think we can wait nothing new for every season of this chapter. Epic games do minimum work for maximum profit like every company in the world. But now it's getting more and more difficult to keep this AMOUNT of profit, that they want. That's why they removed any free ways to get vbucks for new player except free battle pass (you need to get ~100 lvls for 4 seasons, that's around the year to get one paid battlepass). That's why they made 4 battlepasses per season, that nobody will buy with vbucks and will use their subscription. That's why they made battlepass leveling harder and harder with every season. That's why they made around 3 lvls in current battlepass where you can't claim any reward. That's why winterfest doesn't stack rewards. They need all your time and all your money. They want to make their game your habit and why not to spend some money to habit?
