Hats off to the people at Atlus for bringing the hope one step closer to becoming a reality!!!
Not sure if all questions have been asked (in detail), but redundancy doesn't hurt:
1 - Will the training mode have a record function? This is very vital to the competitive scene as this can help create character specific setups, mixups, and situational setups that can make the players stronger.
2 - Will the online lobby system allow for 6-8 players in one room? Also, will there be the option to have 6 player matches (3 people on 1 team vs another set of 3 people)?
3 - If DLC becomes a reality, will it be based on what the fanbase wants (i.e. - poll), or is there some sort of itinerary that needs to be followed?
4 - Will there be special edition character sprites that are console specific (i.e. - Iori's original outfit, Syo Kirishima palette swap for Kyo)?
5 - If a strategy guide is to be developed, how in-depth will it be, and will it give newcomers the right tools to become competitive?
6 - Will you guys assist SNK with building KOF XIII hype by hosting tournaments and showing up to events?
7 - Will the community get notified of any patches and what they pertain to specifically?
8 - Is there any plans on making KOF XIII fight sticks and/or NeoGeo pads with either Hori or Madcatz?
9 - Can we get some classic soundtracks from the older KOFs?
10- When and if the in game tutorial is to be added, can you guys enlist the support of high level players from all around the world if possible? Also, can you make this really in-depth, so that players from other communities can translate over from say SF or MvC3 to KOF?
11-Can we get a massive amount of advertisement in all forms of media (i.e.- TV, internet, magazine, etc)?
12-Will there be a replay channel, where replays from both rank and player matches can get saved, and will be in-depth replay functionality (i.e. - rewind button, ability to upload to YouTube and share, etc)?
13-Will there be better, and more challenging achievements/trophies to obtain instead of "Hit the opponent with

5 times"?
14-Will you challenge/dare the world to become stronger in KOF, and show the world why this game is worth the wait and why it's the best 2d fighter out there???
