yah i was checking throughout the day yesterday, and 2 of my 8 characters got updated
1 Femroe and 1 Viera, neither of which are my MC
it's easy to tell if you "open image in new tab" on the forum pic, if it's a tiny square still in the new tab it hasn't been updated
once it has been updated it'll be a larger size in the new tab, can use Eraden/Mao pic for reference from page 1 of this topic since their portrait has been updated already
