TLDR - Game publishers have learned why go to the expense of doing a complete job on PC titles when the release on console guarantees enough buzz to make PC buyers pony up regardless of how broken and unfinished the game may be on PC. Yea Sherlock, PCs are different from consoles and have different requirements duh, but publishers can't be arsed to fully fund the proper development of PC versions.
