I dont know about any of you but Dan has been stressing over the transfer process since he not only has to transfer things from one system to another but he has to also incorporate a new MicroSd card since the 4gb included one isnt enough for all is data. Monster Hunter itself takes up like 2.7GB so here is a link to all the info that has been compiled. Now let me say he does say things might be different once the new 3ds releases on transferring but he doubts it would be that much of a difference.
Hopeing it helps yall out. Im still deciding on if I want to transfer my data or keep my current stuff on my 2DS. Im not getting rid of my 2DS, it still works and Im attached to it! For those who will want to play monster hunter please let me know and Ill post my friend code on here.
here's IGN's guide that came out today:
They talked about it on a Nintendo Voice Chat podcast recently too.
I'm not really in the market for a New 3DS right now. But I thought about this the other day: if Capcom reworked and released one of their cancelled 3DS games on the New 3DS, I'd buy one instantly. And you know what game that is? Mega Man Legends 3.
All this transfer business. Gaming is too much like fixing a PC nowadays. 
This is just another reason why I'm holding off on getting a New 3DS. I've got a lot of stuff on my SD card and don't feel like spending the extra money right now to get a comparable micro SD card.
Monster Hunter 4 is getting great reviews all over the place. I've never really got into that series, but it sounds like it would be fun.
I'm wondering about how to move data to a new memory card for Vita. The 4GB one they give you is a joke.
