Two things that would make this really interesting:
- If members from other idol groups could register (H!P, Afilia, Idoling, etc. etc.)
- If Paruru would not participate.
As far as the graduates go:
- Hirajima Natsumi is on the top of my list of potential candidates. She always ranked #26, yet she never got a proper goodbye. Unless her scandal put her on the blacklist.
- MaiMai left a long time ago and I think a lot of current/new fans barely even know her. Her solo CD sales have been really low and I haven't really seen her in magazine or on tv that much anymore either (other than that Bananaman show). Even if she were eligible, she might not do well. Her time was five years ago. Actually, when you see her interact with current members (like SKE recently) she barely even looks at them, so I think her days as a typical idol are far behind her.
- Some of the SDN girls are likely candidates too; Sato Yukari, Serina and maybe Kohara, Ohori and Noro. The question remains what AKB48 has to gain by letting them participate, but I guess it's all to get some extra voting ticket sales and media attention.
Really though, there probably won't be that much of a change.
Otherwise, I don't really see much change caused from the new rules.
I honestly can't believe how anyone could say this won't change much. This new system changes everything. It changes the entire game.
Like Data said, even if Sashihara or whoever wins this election, the victory will be incredibly shallow if not everybody participates.
The election will lose all authenticity. I know it's all for fun and entertainment, so I don't want to take it too seriously...
but if I have to spend money on CDs for voting tickets then I don't want it to be for an election that's this manipulated and essentially meaningless.
If the girls have any actual say in all this, they should make some sort of pact and ALL participate. Everybody. Especially Yuko.
edit:
In response to Rust's post, there are indeed several parallels between this and 'real life' politics. In the Netherlands we had one party who was going to be the biggest, the SP. However, in the media they were constantly ignored and ridiculed. The media targeted everything towards a battle between VVD and PVDA, a party which was almost non-existent after the last elections. However, this was so hyped and people were fooled into making a choice between either one of these parties. In other words they basically said, voting for SP won't make a difference because it'll come down to the other two parties. That is a lie, of course, since SP had massive support. However, because the media was so powerful the majority of the people indeed voted for either VVD or PVDA making them the two biggest. SP barely got votes in the end making them insignificant. The most f'ed up thing is that the two "completely opposite parties" now work together and form out government. It's been a massive set-up from day one. Democracy doesn't exist. [/depressing rant].
