Two things you guys know:
1. Online games have to be synchronized between players
2. Sakurai intends for a system in which player skill/data carries over between versions
This means that essential content for the primary multiplayer will be the same across all versions. Smash is a fighting game, so that includes:
- Playable character technical data (hitboxes/frames/etc.)
- Stage technical data, including custom stage options
- All other physics-related stuff, including items and options
These things CAN be changed with mandatory patching, though characters/stages require their cosmetic data or some really good lookin' placeholders.
Let's look at the non-essentials, where version differences and DLC can come into play:
- Character/stage models, effects, animations (assuming no technical changes)
- All audio data
- Controllers and extra commands (C-stick)
- Anything affecting other modes, including gameplay with different rules/physics
- Personal user data (custom characters/stages)
If it doesn't connect to other versions or doesn't affect gameplay, it goes here. This stuff actually takes up way WAY more memory than the essentials -- particularly music and movie files -- and basically means any concerns about the 3DS version's content are completely ********.
I keep thinking there were some other essentials to be listed, I guess that's where you guys come in.
Short version of Toise's crime solving skills: Expect DLC to be music packs and alt costumes, possibly new modes or more trophies or whatever if they're interested in that. Any new characters or stages will be required in a free update.
Other Toise bits:
- I'm gonna rule out on-disc DLC since it's an extremely un-Nintendo/-Sakurai thing to do
- Barring notable bugs, I can't say I expect any patches or DLC at all; Sakurai prefers to move on to new projects after finishing the last one, and there's typically an extreme level of content in his games to begin with
- Apparently Harada absolutely hates paid DLC, good deal
- Still betting that Sakurai's pushing for either the 3DS as a Wii U controller or online play between both systems
