Retired Bioware co-founder Greg Zeschuk is not a big fan of any kind of mid-cycle upgrade for consoles, such as the much speculated PS4K.
Talking to Gamespot he said: "that'd be a gigantic pain in the ass that flies in the face of the purpose of consoles".
Zeschuk shared past experiences on the topic saying that the original Xbox "had multiple different DVD drives" which caused performance differences.
The former RPG developer went on by saying that "they didn't tell anyone that, but as a developer you discovered that you have different performance and sometimes you'd have these boxes of refurbished drives and different brands and different equipment. It caused incredible variability."
