The japanese
version of Street Fighter IV arcade will support IC Cards. With these
cards we can save our "Zennys", which can be used in order to buy new
costumes, wallpapers, ringtones and other stuff.
The arcade version of SFIV will have alternative costumes for every character. They should buyed in the mobile phone game store, using the “Zenny” you winned fighting.
"Zenny" (or "Zeni") is the name of a fictional currency used to represent money in some Capcom games, including Forgotten Worlds, Megaman Legends, Breath of Fire and severall others.
The one with the orange IV and black background shows C.Viper, Abel, Rufus and El Fuerte. The other shows Chun-Li, Guile and Ken. They also posted in the Japanese SFIV oficial site the wallpaper of the next (will be next weekend) location test, which shows Rufus and Ken.
Our ninja Ken told us in our forums there is a new Street Fighter Gashapon series available in the Japanese on-line store (e-Capcom) to celebrate the 20th anniversary and the SFIV release.
These figurines are being made by Panson Works, they're 120 mm tall aprox. and they cost
2.940 yens each one. Ryu, Sagat, Guile and Chun-li the available characters.
