I wonder about how they'll handle the items more this time around, koff~
I think the new battle system will look wonderful, but I agree that certain moves should show a few things better. Some people have already mentioned flamethrower. I wonder how curse, throwing pokeballs, and lick will look. Will the pokemon's tongue be able to actually lick the pokemon, or is it just going to be a special animation instead?
I liked how the bag functioned in Pokemon Soul Silver Version, but not so much in Pokemon White Version. It was nice that the fifth generation added a button that could sort the entire bag, but they combined held items with other usable items that made finding things such as repel or escape ropes a pain. I hope they separate the new bag into more compartments. Pokeballs, Items (holdable and none holdable), etc. I believe when it's separated into more compartments (not too many though) it's handled better.
I'd also like to see what they're going to be doing with the berries. Certain berries, like the anti-super-effective berries might receive an anti-fairy berry (none of this makes any sense. Ignore this sentence inside the parenthesis) I'd also like to see what other berries they can come up with, and be able to use all of them and not just the battle use ones like they did in Generation V. Will you see Pokemon actually eat the berry it's holding? Or will it just be "x ate the berry!"
Also the contest/side quests. What will that stuff look like? Will we have ribbons again? I enjoyed gathering ribbons for certain Pokemon and gathered all the gold leaves for my Kingdra in Soul Silver.
Also, held items. Will we be able to see certain items being held? Like the King's Rock, it sits on the head if I'm not mistaken, so shouldn't Pikachu be waltzing around with a crown? Or the Black Glasses? I can't tell you how much I'll make my non-dark pokemon wear that if it shows. And scarves and hats, weights and orbs. That sort of thing, koffi~
