Welcome to Wiihacks!
No there isn't Any 4.3 System menu for the wii as of yet .
I am going to buy a new wii next weekend. I have heard that there is a new update of 4.3. Is this true? If so, can it be soft modded? I have searched the forum and it says that there is not. Yet, other sites on the web says there is. Any help would be appreciated.
If it is out, chances are it probably won't be on a new console as only very few of the newest have been reported as being on 4.2.
