Question on the manga series "Cross"

[V. Mizrahi]

I've been really into this one manga called Cross. I'm not sure but is there a sixth manga in the series out? I have just read the fifth one of the series. I don't know when the fifth book was released in the US but I don't see the sixth one. Was "Cross" discontinued or is the sixth one yet to be released?

I haven't been able to find any definitive answer either way. As far as I can tell, it just sort of stopped after the fifth volume with no real explanation given. Every site I could think to check just lists it up to five and doesn't have any more info. Sorry, looks like you're out of luck unless it magically comes back.
