Should the PS3 have had Blu Ray?

[fauzman]

At the start, the results of having a blue-ray probably meant much fewer sales due to price. However once the price came down (and the slim version came out) I think the opposite happened - the blue-ray was an advantage over other consoles and probably contributed to ps3 sales significantly. Looking at it overall, I suspect the ps3 would have done better had it had a lower price and no blue-ray at launch (looking at ps and ps2).
