Maybe the impact will be minimal but, as you keep saying, if DK is about maximising revenue then if even one person who would have bought a ST a week or two ago if they had been on sale while riding the crest of the PO wave now won't buy one, we have, by definition, failed to maximise revenue.
Yes, those that regularly get season tickets etc. will wait to buy. But that's not where the potential issue rises. It's those that are not regulars that we've failed to capture while their interest was piqued.
You are disagreeing with your own statement. You can't want to maximise revenue AND delay putting the product on sale while interest is high. Either DK wants to maximise revenue, in which case tickets should have been on sale when interest was at its peak, or he's fine with the delays and missing out on some sales and thus not focused on maximising revenue. It's one or the other.
