Deoxys - E: OU, I've said it before, the only thing Deo-E has over Ferrothorn is Taunt and Screens. Ferrothorn can take hits, actually do damage, and Leech Seed while setting up hazards. IMO, Ferrothorn is far more broken than Deo-E.
On the other hand, Deo-E can use the appropriate Screen to make it effectively bulkier than Ferrothorn- and therefore take more hits.
Ferrothorn can do damage, but given the shitty coverage it's STABs have, it's not hard to bring in a resist. Or even something slightly bulky, given that Ferro will be uninvested.
Raikaria, 15/43 Pokemon in OU have Fighting or Fire STAB. That's more than 1/3. And Then there's a ton of coverage Fire/Fighting moves. Not to mention every Grass type in OU.
I'm gonna be repetitive if I say anything else, but I whole-heartedly disagree with you on Ferrothorn.
Now for predictions:
Latios- I am honestly not sure. I very strongly doubt that it would get a supermajority, but I only needs a simple majority, so maybe... I hope it stay OU.
Deo-E- It'll prolly stay OU. I certainly want it to, because it's supporting capabilities aren't that much greater than those of other Pokemon. I don't think it should even be a suspect.
Excarill- lulz. No, just no. OU, obviously.
Garchomp- Uber. This thing has gotten so much hatred aimed at it. It was in almost every nomination. It created the Great Hax Panic of 2011. I can't possibly see it staying in OU.
Thundurus- Suspect, would be my guess. This thing has a lot of support to make it leave. A good number of voters think it's broken. But it doesn't seem to me that it'll get a supermajority, just because it's not as obviously broken as other things, like Blaziken, Skymin, Darkrai, etc. Because it's not considered broken by almost everyone, I doubt it'll go, although I think it's haters will make it a Suspect next round.
