100 Rings = Extra life being patched in. Button controls are being patched in for the motion controlled wisps.

Awesome. Hopefully at least now the narrative around this game will become a little more focused instead of people homing on the lack of 100 rings=life thing, which was the least of the game's problems IMO. After having stepped away from it for a while and playing Mario 3D World in the interim, I'd probably say the game feels like a 8/10 or so to me. Hopefully now the feedback will lead them to look into tightening up the level design/routes a little more for future games, as well as the implementation of the wisps rather than their control methods and difficulty.
Wonder how Black Bomb will feel though, considering it was pretty clearly actually SUPPOSED to be pretty fidgety by design. I guess this would at least make the missions to use it a LOT less of a pain.
Oh, and a bit of an aside: are there multiple save slots in this (and Generations)? Planning on playing with friends some time eventually, and I'd prefer not to have to override my complete file(s).
