We have made it our top priority to deliver the same quality on both consoles. It was self-evident that it brought some difficulties with it. Both consoles require a different approach. Especially on the graphics section. We had to build a different engine for both versions. We needed a year of tinkering on each engine in order to get the same level of graphics.
Love the delay ;p
