When will Sora and Kairi kiss

Sora and Kairi don't seem to get themselves in a position where they actually admit their true feelings to one another. The only physical intercation they've had is hugging and I think Nomura might leave it at that rather than develop the relationship. This might be done so as to not be biased towards fans who do not support the pairing.
Or maybe because that if they made a kingdom hearts video game I think they will just kiss. Sometimes kissing can be very disturbing for some reason.
