My surprises:
Heatran at #9 is surprising to me because I just don't see it often. I'd love to see what sets they're running: I'm not sure ScarfTran or SpecsTran is good ATM because choiced fire attacks are horrible to be locked into. Since you said you had the data but just couldn't organize it...could you just tell us the most used moves/items for Heatran, if you don't mind?
Xatu all the way down at 106, below Espeon at 54. I don't think people understand how amazingly bulky this thing can be with a set of Reflect/Thunder Wave/Night Shade/Roost. Conkeldurr and the somewhat rare(31st) Scrafty are the only fighting types who can beat it. It can switch into Ferrothorn and immedietely neutralize it with it's resistance to Power Whip, lower end speed + Reflect taking Gyro Ball down a peg and reflecting all it's status moves. From that switch in, you are free to fling around Thunder Waves(If their team doesn't have Conkeldurr), Reflect(Xatu can actually beat some choiced Pursuits by staying in thanks to Reflect, forcing the Pursuiter to switch out or die!) to protect your team/prep for a physical sweeper coming in, Roost up damage taken or just Night Shade for decent damage. It's only disadvantage over Espeon is the SR Weakness...but it also can't be poisoned badly by Toxic Spikes.
Jellicent is unexpected @ 17, IMHO. I just plain don't see it around much and it faces some bad type match-ups right now I think. It is a good Pokemon, though, so I guess it's justified being up there in usage.
Starmie might be at 20, but I swear I see it on half the teams I play. I'm surprised it's not higher. It's also quite good I think, very hard to switch into and very fast, even if it is very frail. Maybe because I guess it doesn't deal high-end damage to Ferrothorn/SpDEF Tyranitar?
Rotom-W is at 10, but I honestly haven't had too much of a problem with it, except with one team I made where no Pokemon could take both water and eletric. It really misses that ghost typing IMHO, but I'll have to try it to see myself.
Finally, Bronzong @ 46 amuses me, I've seen it only once and it didn't do much. I wonder how many of those usages were at the start of April and not at the end...
My expected:
The entire top 5 is not entirely surprising, though I expected Garchomp to be more 6-7.
Volcarona is about right where I expected it to be: not high enough to be a "high end" threat, but common enough that you still must prep for it since it can rip you a new one.
Infernape's position, although surprising to some, doesn't surprise me much actually. I was considering running one myself. Being walled mostly by waters makes him excellent with U-Turn, IMHO, and he can still wallbreak. In addition, most people don't prepare for him anymore, and he can outrun a lot of stuff.
My Expectations:
Strong flying and fighting attacks, especially in combination, look to be "in" this round. Flying/Fighting hits 5 of the top 12 pokemon SE and all the others neutral. The only physical walls looking ready to stand up to it in the top 35 are Skarmory, physically defensive Forretress and some Swampert. I think a rise in Staraptor might result of this, as it can revenge well with a Scarf while not losing much power with Reckless or get more switch-ins with Intimidate and hold a Choice Band, while hitting a lot of top-tier threats hard. Terrakion also looks good this format.
If you can keep SR off the field, Abomasnow becomes a major threat. Tyranitar and Politoed can't come in to weather change, it smashes up Jellicent, revenges Garchomp and slightly weakened Gliscor and can switch into Rotom-W with a slightly bulkier spread. It can't get past Skarmory and some others though and only deals neutral to Ferrothorn.
Leech Seed Breloom and good old No Guard Machamp look as good as ever. I think I'll try experimenting with Substitute Heracross as well...
