As is the case relatively often in recent times, Masahiro Sakurai has used his Pic of the Day on a Friday to show something of a slightly higher significance than normal. This time around it's the user interface (UI) from Super Smash Bros. for Nintendo 3DS, and the focus is on one particular button.

At the bottom left of the main screen are icons for StreetPass and, most pleasingly, Wii U. Before we get to some informed speculation, details from the posts are below.

Pic of the day. For the first time ever, I present to you…the main menu for the 3DS version!! The icons are even animated. The design concept may look similar if you've played other games I've worked on. But we had a hard time making this one because…

The bottom screen displays pictures matching each mode! This was quite a task for the UI (User Interface) designers, but they made it happen. Kudos to them! You can tap the screen to look up additional info like how to play--complete with diagrams.

What will the Wii U button do? Unless there's been an unexpected change in development it won't be direct cross-play between the two versions. However, when making that clear last year, Masahiro Sakurai did state that the aim was to deliver "stress free, easy connectivity" between the versions for transferring customisable characters. With the subsequent addition of Mii characters as well as details on the various customisable move-sets that will be possible, that menu opens the door for that data transfer between systems.

Nintendo may have more surprises in store, naturally, and there are other areas of the UI yet to be explained in detail, including the structure of the StreetPass feature.

Are you still excited about potential features between the Wii U and 3DS versions, and maybe hoping for a little more than transferring customised characters? Do you think you'll buy both versions? Let us know in the comments below.
