I thought that the Season 6 was an edit mistake on ANN since FUNi didn't actually announce anything about it ?? and Movie Z is such an amazing film watched it 4 times already i really hope they do have it.
No, a bunch of sites reported Season 6 and Film Z in addition to the stuff FUNimation actually announced in Otakon, along with an unmistakable synopsis of the events that happened in the arcs included in the batch of episodes and a Summer 2014 release for Season 6. All the sites that had that up ended up retracting the info but it's no coincidence that they all had it there originally.
What happened is that the Press Release e-mail FUNimation sent out to these sites did not mention Season 6 or FIlm Z, but the Press Release e-mail attachment, which most of these sites originally used, contained the Season 6 and FIlm Z stuff. So it was pretty much gonna be something FUNi planned to announce at Otakon at one point, then pulled out at the last second and left a trace of it by mistake.
In any case I doubt an announcement of it could've been planned at any point if they didn't actually have the license. I'd say they're just keeping quiet on it since it's so far from now that there's not much of a point.
