One thing I am noticing is that the rewards for pink boxes are most definitely different. I haven't gotten any R-Gacha tickets (which pretty much looks confirmed) but I AM seeing multiples of things. You don't just get ONE R-Wild, you get three. If you can manage to get a pink box, the rewards are generally pretty decent this time around. What they are taking in making the event shorter, they are giving back provided you can actually get an box that doesn't disappear in 2.3 seconds.

I can definitely confirm that R-Gacha are in silver boxes though.
