Delays are common, and expected as par for the course in the game industry. No one blinks an eye at delays and most games seem to not launch when announced anyway (like most software). The question that matters is, will this actually cost them lost revenue in the long run, or just delay inevitable sales by however long the employees can hold out in a walkout/strike? A delay is just as good as money in the bank in the long run. Will people not buy the product because it was delayed? Will they care why it was delayed, or even know unless it was an in-game message? Some will, sure, but will they still make the purchase? Likely.
