Well, don't forget that
modded 3DSs with video out can be obtained at cost, so there has to be at least a few people who can grab shots. If the Pokedex model remains static, then that's what probably will be used for sites that need it. Just gonna need a lot of cutting out...
The exact technical structure in game will remain out of reach for at least a year or two, barring any surprises. So from day 1, there will have to be a lot of tests done, since there won't be an easy dump of abilities/moves/stats/items to look over - lots of battles, lots of catching, lots of trading. The effects of Pokemon-amie will have to be taken into consideration as well, plus it's effect on the friendship stat as it is (different/same? Does it replace it?).
