"Next Wednesday, Nintendo is holding a major showcase event focused purely on WiiWare and DsiWare games."

The line I've quoted is the only bit of info about the press event in that article. The rest is about a UK conference at the end of October.
Unlikely there'll be any changes in bundles, then. Perhaps it's more of a response to Apple and the App Store, than anything else? I hope that focus on WiiWare/DSiWare doesn't leave out the Virtual Console.. C'mon Nintendo, you know you want to make it a cross-platform service...
