The event will start with a post mortem Q&A panel featuring the game's developers discussing the ins and outs of the development process. You'll be able to get some insights into the development of the idea and what it took to get the game published, as well as ask questions of the developers.
Following that, there will be a Divekick tournament. So start brushing up on your Diving and Kicking skills now so you can go home the Chicago Divekick Champion! It'll be first come first served, so don't forget to get there early to check in.
The top 5 winners will be able to take home their own unofficial Divekickers Hat. If you didn't win one in @fluxwavez's tournament, now is your chance! You too can look like Dave Lang if you place well!
We also have 3 Divekick posters as well for prizes.
Got my bongos and this adapter, and went to testing. I can confirm this adapter works with the DK Bongos on both PC and PS3. I don't see why there would be any issue on PC, but may have an issue on PS3 navigating menus, etc.
On PS3 I started game (Injustice) with a controller went to the button remap menu and remapped buttons to the bongos and then swapped back to get into a game and swapped back again to play the game with the bongos. This may work better on PS3 with Divekick, depending on how much the menu system changed from the game menus at UFGT9. I'll find out once the game is out.
What placeholder art? MOST of the art you see in screenshots at the top of the Divekick Wiki Article is the final artwork (few exceptions due to older builds, etc). It's later at the bottom under the "Prototype" section you see the original placeholder artwork.
But I'm sure that's not the answer you want to hear. I think the art style fits what they are doing, but I've played a lot of the game.
