Shiny Pokemon have become easier to find since even the third generation with RNG abuse. The only thing really increasing with B2W2 is the increase in the chance of a random encounter with the shiny charm. The shiny gift Pokemon and shiny stationary isn't exactly new though, it just hasn't been used since Generation 2. RNG abuse isn't even that hard on BW anyways, especially if you have a DS Lite or original and you find a good guide.
