Should the HTC One/Galaxy S4 Google Editions cost so much more than the Nexus 4?

Question: If this phone is coming without zoe or any of the HTC optimizations then it is essentially a Nexus 4 with a better screen/processor and a camera with a lower megapixel count. If this is indeed the case then can the price of $599 be really justified or the $650 price tag of the Google edition S4? Now I know why it is $599/$650 (so don't ya'll come attacking me) but being much more similar to the Nexus 4 on the software side makes me question the price a bit. Just want to know what y'all think.
