Xemnas had his memories I thought. I thought Roxas and Namine were the only ones who didn't have memories? I know Xehanort lacked memories. I guess we will have to wait and see.
I too, am looking forward to the game (why the PSP though?) and I'm hopeful that 358/2 will explain the Nobodies and Organization XIII more fully. I'm sorta of hopeful cause Nojima is not writing for either title and instead we have Daisuke Watanabe (who co-wrote Kingdom Hearts 1 and wrote the awesome KH: Chain of Memories). He seems to have a better sense of pacing and a strong ability to bring out heartfelt moments of the characters without feeling overly cheesy, imo. I just hope Nomura doesn't pull another KH2 and decide that neither game should explain everything for the sake of making more sequels and spin-offs. :rolleyes2This is why I'm most interested in Birth by Sleep. Given that Terra and Ven both visit Destiny Island, I expect to see the connections take shape in that game. I feel as though 358/2 Days will cover the Sora/Roxas/Ven thing more fully.
