The only reason they reached for something, was because they did it before, on the same platform, when the barbarian was announced. We'll see if it was just nothing.
It makes no sense however. Why tease at all, during a time where people are sort of expecting to hear something? We are nearing 4 months, patch time, that is. We are expecting a new patch to hit soon.
Again, we'll see. Could be nothing , could be a tomorrow's announcement. Larian's communication was not always direct anyway.
