I got the two pins without the newsreel. I didn't feel like using more points for something that was given away for free. Plus, the random cover was disappointing. Had they given you one of each, I would have been likely to get it.
Also, I think it would be hard to merge your DMR account with your D23 account to make these exclusive. They already have enough problems with getting people's accounts activated in the system to buy stuff from disneystore.com as well as register for events. An besides, D23 members who collect the pins will hear about these and get them, so its not a huge deal if a few non members who collect pins get them too.
