In the future, I've noticed one thing that you can use to gauge whether a CE/LE/SE will be overproduced. If the packaging is extravagant or an included extra is something that would need to be special produced (and there isn't many companies producing such things), the item in question will probably be overproduced.
This is due to the company needing to order said component in bulk in order to get it to a reasonable price for mass market consumption. Take Alan Wake or Bioshock 2 for example, with Alan Wake, Microsoft had to order the packaging in bulk (the book style packaging) as well as the book in bulk. With Bioshock 2, Take 2 had to order both the Vinyl Record (which are incredibly expensive to print if not in a bulk quantity) and a 200 page hard back book. In both cases, neither company could afford to put out a small print run and make the product truly limited.
On the other hand, both the Mass Effect LEs and the Demon Souls LEs came with nothing extravagant. Therefore it was perfectly logical for EA and Atlus to keep the things truly limited, they had no need to order in bulk.
This same rule can be applied to almost all of the other LEs I've seen people say they regret: GoWIII (that box probably needed to be bulk ordered), Batman: AA (no way that Batarang was cheap, or the case for that matter), etc.
I don't think things like action figures need to be bulk ordered since there is several hundred places that can make those.
In any case, I'm going to apply this rule to the Duke Nukem CE that was announced this week and put my money on "not limited" for the time being. I know they've said it was limited (and the picture clearly shows a limit of 2,000 for each platform on the certificate), but I think that is just hype. The picture has a "subject to change" disclaimer underneath it in any case. That bust seems like a "bulk" item to me.
In any case, I'm pretty satisfied with all the LEs I've bought. I always buy the LE over the standard edition if there is DLC included, because I can usually sell the DLC to bring the cost of the LE down to lower than the standard.
