1. Again, I originally had exclusivity in quotation marks. i obvs dont mean exclusive the way LV, Nike Air Mags, and Lamborghinis are exclusive. I know we are at the point that we ask when a shoe will rerelease, but if I wasnt able to cop a shoe last time it released, have to patiently wait 4-7 years (or more for some shoes) to try my luck again, with no guarantee that my luck will be any better, then I think it is fair to call them exclusive. Hell even a colorway I did get I am reluctant to wear if I really like it, because when it comes out 6 years later, I might not be able to cop and have to wait again. I assume that is why people cop multiple pairs of their favorites if they can. It is also the reason the can sell terrible quality shoes for so much. I got the Fire Reds even though I hate this version with a passion. I doubt I will ever wear them because I cant justify that purchase, I would much rather sell them. I got the Olympics VIs, wore them like 6 times and I am trying to sell them because I caved. The blue is too dark, the shape is off, the sole yellows even if you dont wear the shoe, and the paint job is blotchy
For instance I wasnt able to grab the Concords or the BCIIIs last year (my phone broke and I didnt expect this post Concord mess), I refuse to pay aftermarket Concord prices and I am hunting down the BCIIIs for a decent price. I outgrew the 99s a long time ago since because was still a child and it is going to be at least 2017 by the time they drop again. How can you say JB is not using exclusivity as a large part of their business model?
I would say it is more exclusive than ever. Prior to 2010 if you wanted a shoe you could stroll in the store and grab a pair much after release date with few exceptions. And they are exclusive enough for you to seek out previous releases (like in your sig).
2. i do not think that is their motive. If they decided to drop these both tomorrow, completely unannounced, they would still sell out instantly. You know this, I know this, and they certainly know this. They have released very popular shoes a week or two apart throughout the year. Either way their consumer is coming out with something. If they wanted post Christmas money, they would announce a new colorway instead if pushing back revenue they will make either way
