I'm a bit quicker off the mark with the dex size update! Let's see what we got ourselves today.
Kanto - 45 (44 original, 1 regional variant) (+1)
Johto - 24 (15 original, 5 cross-gen evolutions, 4 cross-gen pre-evolutions)
Hoenn - 28 (25 original, 2 regional variants, 1 cross-gen pre-evolution)
Sinnoh - 31 (19 original, 9 cross-gen evolutions, 3 cross-gen pre-evolutions)
Unova - 52 (all original) (+2)
Kalos - 23 (22 original, 1 cross-gen evolution)
Alola - 20 (all original)
Galar - 20 (18 original, 2 cross-gen evolutions) (+1)
Total - 243 (+4)
Percentages (Rounded down) (Not doing % of overall regional dex this time b/c it's tedious and too little has been added):
Kanto - 29% of Kanto mons
Johto - 24% of Johto mons
Hoenn - 20% of Hoenn mons
Sinnoh - 28% of Sinnoh mons
Unova - 34% of Unova mons
Kalos - 32% of Kalos mons
Alola - 22% of Alola mons
Unova's officially the leader! The more of their mons are revealed, the more hilarious the initial fearmongering over their dex getting the shaft becomes.
As for Sirfetch'd itself: I love it. The mere concept of a Farfetch'd evolution would be enough to entice me, but it being such a radical change type-wise is the cherry on top. A pure Fighting with moves like Roost, First Impression, U-turn and Defog sounds so cool! With that said, I find it curious that it seems as if there is no Galarian Farfetch'd to precede it. The description of how it evolves (by going through many battles) is also vague enough to not really justify or require it to be a region-specific form. Have GF at least partially shook off their fears over standard cross-gen evolutions and given us one? Remember, this isn't a regional variant of an already existing evolution like Marowak, this is basically a new mon in GF's eyes. Also, he's Sword exclusive, huh? Guess I'm getting that game then. Or maybe I might pick Shield for Bea. The exclusives are making it hard to choose for me this time around!
Very interesting that only the sword logo shows up. If its only for sword, what does ahield get?
Delibird evolution or I go sicko mode.
