I'm also planning to get both. After all, I think they'll be the last two games worth getting for the Wii. I can afford to get both of them.
I'm pretty sure I'll enjoy Kirby, and I feel obligated to play Skyward Sword for the sake of all the people on ZD. Also, I've beaten all the other mainstream Zelda games, and I don't see a point in quitting now, or letting this one slip by. Especially since it is poised to be popular.
I think that people don't pay enough attention to the Kirby games, though, and really underestimate them because they're not as "serious" as Zelda. That could just because this is a Zelda site, of course, but it seems to be true in general as well.
