Species, OHKO, and Evasion clauses, in no particular order (well, actually Evasion first, Species last, but that's just me). Getting rid of any of these clauses would shake things up to the degree that many of our decisions regarding Uber/OU pokemon could be rendered irrelevant. I also think that clauses in general do more to cause the game to be "incomplete" than banned pokemon, so we better have extremely good reasons for having them.
As for the suspect pokemon, I've always been of the opinion that we should pretty much test every potentially OU pokemon at the same time. From the beginning of DP and maybe even a little beforehand, I remember AA proposing that we pretty much start from scratch in terms of bans, and I still to this day believe that that is what should have been done. That said, I expect Manaphy is the most likely of the five you listed to become OU (although it seems Ho-oh and Deoxys-L are becoming suspects as well, which makes me happy).
Garchomp testing will/should happen after the other suspects are finished; it "had its chance" and I'm not sure Platinum did all that much to hinder it, unlike, say, Deoxys-S (I won't go into that).
Stealth Rock should not be removed or tested, and it certainly shouldn't gain priority over anything listed. It's a new clause, and we need more than "I hate playing with this move all the time" to justify adding another clause in my opinion.
Arceus in Ubers is being discussed in PR of course- I agree with Obi's position but maybe I'd say differently if I played Ubers. That said, testing is totally irrelevant when it comes to Arceus so whatever.
I personally don't see why allowing Lati@s into OU is even being considered. Its ability to effectively utilize items, including Soul Dew, is part of why its uber. Its the same reason why we didn't ban Yache Berry on Garchomp and allow it into OU, before Platinum.
If Lati@s without Soul Dew were considered fair game in Standard, then we could place the blame on the item and ban it from standard play entirely. The situation is different because Yache Berry is only broken on Garchomp, but can still be used by other pokemon with non-broken results.
Im Thinking that Garchomp SHOULD be back in OU. Alot of things Counter it.

Anyways, Its not that Frightening, Its just like Salamence.
ok, that obviously doesn't belong in this thread as it has nothing to do with the transition from DP to Platinum. We already decided that Garchomp was uber in DP, so the only real question that may exist is whether Platinum really did anything to change things.
why the attitude lol. Your post definitely made it seem like you thought Lati@s would be tested in standard with Soul Dew, so whatever.
I'd also like to specifically bring up Mew because of the discussion in PR regarding it being taken off the suspect test list. I think it should remain a suspect because Dual Screen Deoxys is no longer OU (not that it matters- it was a suspect anyway so that argument was kind of silly). While I wouldn't be surprised per se if, say, Dual Screen Azelf + Mew became a silly gamebreaking combination, I don't think we can come to that conclusion without testing when there are certainly ways to stop Azelf, while Mew itself arguably didn't even improve from DP to Platinum (correct me if I'm wrong, I do realize he gained a few moves but I'm skeptical) due to inaccurate hypnosis and an even more offensive metagame.
