You aren't the only ones that got a 3DS for the sole reason of getting KI:U, for I was one of em, too. Honestly, I felt like it was some kinda interesting destiny on how this came about.
1: Saw first Brawl trailer. My main focus was towards Pit the most and wanted to main him
3: Saw more footage as time went by, and still wanted Pit.
4: Saw Japanese footage of him since they got the game in January as opposed to March 9th here. It just wanted me to use Pit even more.
5: Tried and enjoyed using Pit, and he was gonna stay being my main like with Bowser. I also liked Palutena a bit in the cutscene somewhere.
6: The KI:U trailer showed up, and got a 3ds shortly afterwards, waiting for the game to come out.
7: Got KI:U and loved it, with the exception of growing arrogance and generic sets from players in the multiplayer bit, but that's another story. But anyways, the game has made me love Pit and Palutena even more.
8: Heard about Smash 4 and wished for Pit and Palutena, and we already got Pit. During this time, still mained Pit in Brawl.
9: All this waiting and teasing bout Palutena's chances (whether it's the leak that's still not debunked, her stage, all the KI content so far, and definitely Sakurai's trolling in the Smash Direct) just hypes me up for Palutena more and more.
This is subject to change or growing.
And look where at we are now. The 2 final pieces to this thing is for Palutena to be revealed, and for me to main her along with Pit (and Bowser). Let's just hope we'll be rewarded with her presence in the game as a playable character.
