New copies of NWC-enabled games appear to be getting re-releases without the logo.
At least one Wii game has been confirmed for a new print run that omits the Nintendo Wi-Fi Connection logo from the packaging.
We have received a photo of a new copy of Super Smash Bros. Brawl without the logo. The case also has an altered ESRB rating logo without the "Online Interactions Not Rated by the ESRB" statement that would usually come below it.
With the closure of NWC imminent, it seems Nintendo want to make it clear that these last-gen titles will no longer have online functionality. It is currently unknown just how many other titles for Wii and Nintendo DS are still in production sans the online connectivity information.
Thanks for the tip-off by Syrenne McNulty of 4 Corner Games.
