Cross-Gen and Last-Gen Games. Why?

A lot of games had probably started development well before November 2013 and what devs had in mind were decent PS360 sales still, and flops in the shape of Wii U and Vita. A lot of games are selling way better on next gens, but admittedly are more frontloaded while PS360 versions have better legs which is understandable considering the install base.
I think that every game that started development in 2014 and beyond won't have the burden of last gen consoles, it's pretty obvious that it's barely worth it now, and won't be worth it in 2015 and later.

This does have me a little worried about Borderlands: The Pre-Sequel, although I readily admit that my worries may be unfounded. I don't want the game to "flop" in comparison to its predecessors and thus be written off as a franchise, or at least be relegated in terms of priority. When it comes to release, how many people will be owners of new-generation hardware, or at least be well into the process of saving for it and thus less likely to make last-generation purchases?
