I was rooting for Pit's inclusion in SSB since the first one. Kid Icarus wasn't the greatest of games, but like all nintendo games of that era, it had a certain charm to it. Also it was unforgiving, which is something I love about it. I still play it sometimes.
A sequel could work, if they make it in a god of war-ish scale but with a lighthearted touch. Which with all the mario sequel-itis we're getting from nintendo lately, I doubt it could happen.
One can still dream tho, I wished the same for bionic commando, and I got a next-gen sequel and also a remake in glorious 2.5d, can't ask for more.
