I am always on the look out for the "next big thing". For the past couple of years the Pirates versus Ninja battle has raged on, and the winner looks like Pirates. So I have kept my eyes peeled for the next battle, and here are some of the possibilities:
Steampunk vs. Clockwork - This one is my favorite, one group derives power from steam versus another that makes intricate machines powered by winding. They are both really cool, but maybe too close to be an easily divided fight.
Vikings vs. Aztecs - A couple years ago it looked like the vikings were coming on, but not much happened from it. I think if they get paired against the Aztecs (Mayans/Incas) it may be the opponent they needed, the problem is that Aztecs and Vikings may be too different from one another. And Aztecs may not be glamorous enough to get people on their side.
Vampires vs. Vampire Hunters - This seems like a natural rivalry, but it really doesn't get much play. But think about it both are generally thought to be really cool, yet both are enemies. You can't loose if you pick either side they are both just awesome.
So keep your eyes peeled and see if any of these rivalries pop up. It might take awhile, but as the Pirate vs. Ninja thing dies out something will take its place.
Bonus: While I am on the topic of following current trends I would like to get everyone caught up with the latest fruit trends: Awhile ago it was Peach, then a few years ago Mango was the big new fruit flavor, then not too long ago Pomegranate made a showing, and currently Acai is the hot fruit.
My pick for the next hot fruit is Goji, although I could see Rhubarb make a run for it. (But rhubarb isn't a fruit, so it shouldn't count.) If you see any Goji fruit drinks let me know, also if you have a pick for the next hot fruit or versus battle throw me a comment.
