There is no way of being able to transfer pokemon from one to another, yet. I am pretty sure you will need two ds systems.
You will get a 30 day trial which should be enough time to transfer them all. I would advise you make sure you have all that you need in Gen V before the pokemon bank opens (if you don't intend to pay the 5$ yearly fee). Though, I'm guessing competitive players will, in order to keep using gen IV move tutors... You could even transfer all the way from gen III if you have a DS O.o (4 gen transfer makes my head spin)
I've been a bit confused about transferring Pokemon over from HG/SS and later. Will we essentially have to jump them over to B/W, and then we'll be able to simply transfer them over to the Pokemon Bank?
Thanks!Gameboy games to P/D/PT.
P/D/PT + HG/SS to B/W
B/W to B2/W2?? (I don't know if you can transfer straight from older DS games to B2/W2 or if you need to get it to the originals first
Then Pokebank Transfer.
I will be pulling out my Gamecube to transfer some Gale of Darkness pokemon all the way to pokemon X/Y for fun and for the rares.
Ontopic with the Rates. Guys, you bought a 3DS/3DSXL and Pokémon x/Y, but I don't know why everyone is upset with a little $5 to pay for Pokebank. I saved $30 buying my 3DSXL and pokemon Y game together. That pays for 6 YEARS if I choose to do so.
IMHO, I feel that Pokebank is DEFINITELY worth the $5 a year. I was sad at first cause I thought it was monthly, but yearly... that's no problem!
