I'm completely open-minded and buy the system which will get Pikmin, Zelda, Smash Brothers and F-Zero...oh
Yeah, the Wii-U will be very likely. But I may get more consoles, if they get the right games. A good Atlus-game may be an important argument for one or another console (but first I have to play Etrian Odyssey 4). I also like the idea of Kinect, but I will only buy that if a good game utilizes that.
That said, I don't think anyone is really openminded. You all have your tastes that will probably lead you to prefer one device over the others. And that's completely fine.
Oh, I will try not to buy any of the devices too early. I want a good lineup, if I pay for the system. But people get weak. I bought the 3DS after only a year, because it had a Zelda-limited-edition. I couldn't resist. Such things might happen. And - even if I didn't knowed that at the moment of my purchase - it was just the right time to get the system. Short after I bought it, RE:Revelations came out, then Dillon, then Kid Icarus. And Fire Emblem and Etrian Odyssey will follow. I'm pretty happy with that, but I didn't know at the time I got the 3DS.
