Well, in comparison to last week's "last week", this won't take very long.
The week started with a 30 second teaser of Fragile, a new post apocolyptic RPG for the Wii. Then came news of Coded Soul coming to the PSP, with hints of a link-up to PS3's Folklore. Then we had a slew of releases from the UK.
Arguably the biggest news of the week was the announcement that Square-Enix were bringing over Odin Sphere for the Europeans in early 2008. This 2D-ish RPG, while criticised for its slowdown during major battles, has been receiving a lot of praise for the graphical style and gameplay. Finally, there was the introduction video from Yggdra Union for the PSP. Although, you shouldn't be seduced by the graphics exhibited in the trailer, I don't mind if you get seduced by the music which is the best I've heard from a trailer for a while.
