Yeah they should. I don't really see SoRik together like that.. they're best friends, and I feel that Sora's more comfortable around him than he is with Kairi because hey, Sora kinda seems like the type of guy who's challenged when it comes to relationships and with girls. Like with that one hug scene in KH2. Who wouldn't be shy if their crush just ran up to you and gave you a big bear hug? Sora acts more like Riku's younger brother if you ask me.
That being said, I don't think there's gonna be chaos between shipping fandoms. Nomura's been throwing out so many hints of Sora and Kairi's romance, I mean I get it if you don't ship them, but people should get that feeling that they are eventually going to end up together. ^_^
