I've had a theory for some time but nothing I've actually researched on. The 3DS has 2.0 flash memory while the Wii U has 32. That is a big leap. That being said, it's in obvious the 3DS will limit the Wii U in some aspects. As well, Sakurai had gone on to say that both versions will share the same roster library. This is why many people are claiming that the roster will be forty or less in size due to this limitation. However, I have a theory where the roster can still be 40-50 in both versions.
SSBB was full of additional content. It had a horde of stickers, trophies, music, items, the stage builder, the failed SSE, event matches, and even the classical demos. While all if those were fun, it did little to add to the actual gameplay. I feel that in SSB4, gameplay and characters are receiving a large focus. So here is what I am getting at:
In order to conserve space in order to create a large yet diverse roster, Sakurai and his team forgoes adding a large amount of content for the 3DS version and focuses more on customizable content while the Wii U is the more traditional Smash experience? That is to say that additional content is minimalized in order to conserve space in both the 3DS and Wii U?
It might be a pipedream but it is something that I find realistically happening. I'm trying to find the interview where Sakurai commented the differences between the two versions, both having the same roster but different stages. Is it unrealistic to suggest that additional content in both versions will be different? The 3DS having less trophies, stickers, music, and such? How many people will be disappointed that we didnt get 100+ songs in both versions as opposed to Ike, Lucario, Lucas, Toon Link, etc being cut? Would people prefer a downsize in content but a 40+ roster size?
I am also trying to figure out how much total space the Brawl roster took and compare that to the 3DS memory. In my opinion, by finding out how much memory the content in SSBB, we can guesstimate how much will be needed in the 3DS ( if that makes any sense). Obviously, cutting a few trophies does mean it will free up the roster but a possible decrease in overall additional content may allow a few spots on the roster to open up. Like I said, I'm unsure as to how much memory stages, trophies, or characters takes up so this is all a untested theory.
Suggestions?
