I know I'm probably gonna catch flak here...but my thought is...exclusives should remain that...exclusive.
I've backed a lot of things in the past, and nothing is more annoying than paying a little extra for an 'exclusive' that a year later becomes, "Hey anyone want one, We're just GIVING THEM AWAY!!!!! WHEEEE!!!!!!!!
Now, if the Legendary/Urbie are touted as being exclusive to the Kickstarter, and CGL wants to sell them at Cons...sure, OK, but to then make them available via any old online store, suddenly something folks paid 'extra for' because it was advertised as being exclusive, is bad faith.
Again, my thoughts, and is just as valid as someone's thoughts they should be available to anyone who wants one.
