After viewing the new gameplay vieo, I calculated some of Honedge's stats (HP, physical attack and special defense), assuming 0 IV and 0 EV plus a neutral nature for both Honedge and Octillery, gen V formula for stats and damage calculation (the formula didn't changed since gen III iirc), and no power change for the moves used. Honedge has a base HP stat of 72 or 73 and other values need to know the random factor for damage calculation. Also, because we can't know how HP exactly loses Octillery, I'll assume 22, but it can be something like 25 actually.
Honedge's attack (assuming 22 HP lost of both Aerial Ace and Shadow Sneak, both having the same effective power due to the later's STAB) :
> assuming the random modifier being 100 %, Honedge has a base attack stat between 99 and 104 ;
> assuming the random modifier being 85 %, Honedge has a base attack stat between 121 and 128.
Honedge's special defense (I assume Octillery's first move being Signal Beam, the second being obviously Octazooka) :
> assuming the random modifier being 100 %, Honedge has a base special defense stat between 61 and 63 ;
> assuming the random modifier being 85 %, Honedge has a base special defense stat being 50 or 51.
Honedge showed as male is kind of weird. It is an inorganic steel sword, it should be genderless like Magnemite or Klink IMO. I hope it will get some good egg moves.
Also, am I the only one who doesn't expect a lot of Pokémon related to old ones ? I know Newtwo and Sylveon being ones and gen VI being an even generation, but they are the only ones revealed at this time and at this time some new Pokémon like Mime Jr. or Bonsly or Weavile where already revealed back to pre-Gen IV period iirc. While I don't expect other (pre)evos of older Pokémon, I don't dismiss the idea about some of them in the new gen. I just don't want to wonder for some new evolutions and being disappointed with a generation similar to gen III, with only Azurill and Wynaut being related to old Pokémon.
