Zan is Japanese for Slash, that's why it's called Dynamic Zan in the fiscal reports and Dynamic Slash in that conference teaser. The final title is apparently Zangeki
no Reginleiv with NeoGAF people saying Reginleif is the name of a valkyrie and the game supports Motion Plus (and the classic controller, I wonder if that would mean right analog controls the sword, supposedly the PS2 mech games Sandlot made had controls like that...).
CERO D is probably more like the PEGI 18 rating (which isn't as rare or porn related as the AO and Z ratings), 16 tends to be given to games that get a T in America.
Sandlot is making Dynamic Zan. Cing is making Hotel Dusk 2. Are those 1st or 2nd party dev studios? It is the same as ED and Geist.
Sandlot is independent of Nintendo, they usually get published by D3 Publisher.
If I remember correctly, KDR has the homebrew channel for import games, or else I'd be wondering if he's now planning to buy a Japanese Wii.
Of course I've got the HBC, this is Europe! A Japanese Wii would mean I couldn't get US-only games.
