IDK, he may be right, but personally, I believet that they are not necessarly priortizing either version, but instead co developing the X1 and PS4 versions together.
This is not like 7th gen where the 2 platforms had darastically different architectures, they are both X86, they both have the same processor, same type of GPU, and same amount of RAM. While X1 may have some challenges asociated with it's RAM speed & smaller GPU size, it is still very similar to the PS4 HW wise.
