I'm really sorry if anyone has asked this but there are so many pages of replies that I don't know where to look for.
Well, my regular Nintendo 3DS XL arrived today (WORST...TIMING...EVER!) and it came with the firmware 6.2.0
I didn't connect it to the Internet but I'd like to ask you: what do you advise me to do at this point?
There are two options:
1) GW won't support 9.3. Then you should wait until there may be a game with 9.0/2 and update thorugh this.
2) GW will support 9.3. Then you should update.
I suggest you don't do anything with your console and wait until there are further information.
EDIT: too late :/
