A few days ago the Japanese carrier Docomo announced a improved version of the international Galaxy SIII, the version that they announced is called the Galaxy SIII Alpha. Its has the same Exynos 4412 Quad core chipset but this time its clocked on 1.6 Ghz and its also has 2 GB of RAM. But the most interesting part is that the software has the multi-view feature built-in, so you use 2 apps on the same time just like on the Galaxy Note II. Its unclear if this feature will also come to the international version of the Galaxy SIII.
Below you can see the multi-view feature on the Galaxy SIII:
