Well not exactly lazy, but they are not going to take the additional time and money to make both run at the same resolution.
Make no mistake about it, Xbox One is more than capable, but in the case of PS4 versions running at a higher resolution because most of those game were built using older style pc architecture, so it easy to port those over with medium setting.
This story is far from being over.
You don't get it the only way those developers can make those games on par is by gimping the PS4 version,there is no way around that fact there is a gap in power that can't be close by software period and will never be make up.
There isn't a single scenario were the xbox one can even catch the PS4,the whole excuse about using older style PC architecture is a joke,the xbox one has a GCN gpu just like the PS4 those have been here since 2011 man.
Old engine or new engine the PS4 will always beat the xbox one.
