Oh no, this is hyperbole I feel. All thats happened is they got rid of the old Coming Soon Schedule they've had since 06. This happened a couple weeks ago.
You can still access Virtual Console games and lists and everything. I imagine if anything on Wii VC ever gets scheduled again it'd show up herehttp://search1.nintendo.co.jp/search/so ... iew_order=
NCL did some reorganizing with the way 3DS eshop games coming soon are displayed awhile ago too so that it would show up on those search pages. I think its just they wanted everything to be in-line with the way they display their full digital schedules now.
Please don't blow this out of proportion people, maybe Japan wont see another Wii VC update but they didnt up and get rid of everything related to it.
