Accounting for,
The 57 4th gen OU/BL (aside for Rotom forms)
Rotom forms being tiered separately
The many existing non OU pokemon given new tools for a possible tier change
The vast majority of 5th gen's pokemon being competitively viable
This will likely lead to huge gaps in ability between the top 50 or so NUs and everything lower (and NU will in effect be gaining the same number of pokemon as 5th gen's fully evolved non Uber/BL).
It makes sense for a change like this to take place now, hasn't the current structure been around since 3rd gen? We've gained 263 pokemon since then (not counting alternate forms).
Uber/OU/BL/UU/NU are still up in the air, but many current favorites will fall from the higher tiers and 5th gen's power creep will definitely affect NU while some pokemon are left even further behind, to languish in obscurity.
Look at it as though UU didn't exist in 4th gen, many 4th gen NUs wouldn't have had a significant place in competitive pokemon.
