To be fair, Smogon's RNG research thread isn't exactly high-profile (mainly since it isn't stickied and doesn't see much activity besides researcher posts), and Serebii has a lot more in-game info.
Regardless, this isn't particularly important for VGC. While it will be good news for new players after BW2's international release who may lack a BW1 cart, it doesn't offer any new options outside of Little Cup, so any discussion about it is probably better suited for the Wi-Fi forum.

RNG is kind of like firing a gun. Why shoot blindly in every direction until you're lucky enough to hit the target when you can just take the time to aim properly and hit it with one shot?
