The goal with the Power Up reprint is just that, a reprint. One that works with either version of the main game.If you already have the old Power Up then there is no reason you need to buy this version. Just ignore it.
The extra Evolutions are not useless. There is nothing preventing you from using them with a different monster. Or drafting them, as per the alternate options presented in the rules.
We also don't know what form the potential "Tokyo in New York" expansion will take. Maybe it will be similar to Power Up and have Evolutions and a new monster, maybe they'll go a different direction with it, we don't know yet.
