It was said somewhat earlier in the topic, but z3 is going to happen near the end of July or the beginning of August. As for the specifics on how long the event is going to be held for and how things were going to be presented, that was a little up in the air; well for the most part the categories were fished out and the date was set to be as I mentioned.
Otherwise another point for it being in the future like that is so that in the meantime those who are interested in being a part of it can work on their projects and/or the ZFGC staff can figure out how to best support that effort through setting up team board spaces if necessary (currently the Sponsored board has to be looked into how to improve its use), improving the GM Minish Cap Engine if that would help you out with a programming concern (there was talk in the staff area to where a feasible plan was hatched to make it seem more open), or whatever within reason.
Also in addition to the GM Minish Cap Engine stuff, which I am lagging behind on a bit due to school kicking my brain in, I was thinking about expanding my GB Pokemon Engine - but that's a pipe dream because even though I got the bike into it efficiently, the battle system is somewhat dependent on a stable menu system which I have not yet implemented. Ugh... but yeah, otherwise if I had enough time and patience to tinker in Java, I'd alter LateralGM such that team projects made in Game Maker could be synchronized between team members and things like objects could be exported from a Game Maker file and reintegrated into other Game Maker files. Although that gets complicated.
