Hp(95): At Lv 30 Sylveons HP is 103. Since there's no nature that decreases HP, a base stat of 110 or 130 would be far higher than 103 (Lv 30 Pokemon with base stat of 110 = 106)
It really depends on the IVs. Like I said in my previous post, 31 IVs in HP would make it have exactly base 95 HP, but if it had 0 IVs, it has exactly base 110.
What I noticed in the demo, is that Mewtwo had a consistent HP stat of 353, which means that they gave it to us with 31 IVs in everything(I'll assume). So, they most likely gave us all the other Pokemon with 31 IVs in everything. Meaning Sylveon has a HP stat of 95, Fennekin has a HP stat of 40, Froakie has a HP stat of 42, Chespin has a HP stat of 57, and Helioptile has a HP stat of 45. :]
I agree with all of the other stats. After watching that footage with Sylveon taking hits from that Politoed, it's guaranteed its Special Defense will be its highest stat.
