we really didnt need another thread on this, but if it's a civil "why is it like this" and not a piss on Lucasarts and Obsidian thread maybe it can stay.
IMO there's 2 reasons, who knows which.
theory 1- the port just wont be done. They need time to finish. Remember, it was originally slated for both to be out in Feb.
theory 2- Lucasarts wants to spread the cash input from a blockbuster like this (it's the only surefire game they have slated right now) over 2 quarters, so the financial reports looks better.
