Unicorns are all well and good, but come on - how often are you ever gonna put a unicorn on the battlemat? Unless you've got an evil party or an evil unicorn, it ain't too likely. And even if you do, you're only ever apt to need one.
For that matter, how often are you ever gonna put a unicorn in your game at all? D&D doesn't really do unicorns. They're in the manual because they're a big thing in fantasy and the designers feel obligated to include them, but the game has never made much effort to do anything with them.
Now, if 4E had rules for unicorns as ranger companions, or paladin mounts, you might see some action on a unicorn mini. Although 3E had rules for those things and it didn't help, so maybe not.
That was my point when I noted that any unicorn would be an uphill sell.Unicorns are all well and good, but come on - how often are you ever gonna put a unicorn on the battlemat?
In addition, the RPG department needs to work hand in hand with the miniature department. Unless these adventurers are being cranked out in a week, there should be some lead time to make miniatures that are appropriate to the game. We're getting Norkers now? Now? Seriously? Like two years into the game? Like no one knew Norkers were going to be in the second adventure before it saw print? Like the miniature developer bought his own copy and said, "Wow, look, Norkers!"

To be fair, we have a druid in our 3.5 game who summons unicorns occasionally for their abilities.
