Even the good ports like Deus Ex: HR and NfS: Most Wanted U didn't sell good.
Most publishers have their teams for simple porting jobs and they have to decide how they use this manpower / limited resources best. Will a PS3/360 port to Wii U be more profitable (more optimization due to hardware limitations needed, 3rd party seen as "necessary evil" by big parts of the core base, low sales for most 3rd party games) or will a PS3/360 port to PS4 and/or XBO be more profitable (less optimization and therefore less time + money needed, 3rd party games widely accepted by big parts of the core base, much better sales of 3rd party games)? Gee, it's a hard decision!
