Pokemon is a japanese entertainment. They need time to translate things anyways. :/
I was hoping for an opal title, since Giratina was named after Girasol or the Fire Opal. So CoroCoro should come right now and confirm this. Heh, Volkner isn't gymleader anymore? And Regigigas Sky Form? How can that thing possibly fly? Eh, I guess it's quite believable, unlike that terribly made announcement posted a few weeks ago. I'll look forward to it.
To be honest, I'd expect (and want) a GS remake, rather than a beefed-up version of Diamond and Pearl.
I'd call them Platinum and Iridium (Platinum for Silver, Iridium for Gold).
But that's just me.
Oh, come on, who doesn't want to see Johto in the DS?
Besides, D/P has flirted with Johto too much (The Red Gyarados, Jasmine, etc).
Maybe its a sign platinum WILL have johto in it.
Who knows?
