It gave some great battle footage, and the HP Bar looks a lot more improved from that of DPPt. It has more of a sleek style and the curved/slanted end to it was a great touch. Like I stated the Notch Eared Pichu's sprite was definitely put out well, and Volt Tackle for the one Pichu was a good choice as before it was only available through breeding. So, having that as the special event attack makes perfect sense. This is the most wanted event for me, because even though Pichu is a well known Pokémon, I still like the fact that they went out and made a difference to it.
The heavy snow area, this is definitely a great visual shown. It tells that the games will have weather adjustments, which is something realistic and would be a nice touch for Johto. Not to mention, the area does look like it could be more suited for the top of Mt. Silver, meaning there could be more than before to explore in that once mountain. As for the hint for Shaymin, another event would be nice, and if it is in Kanto as said, then I see it being held near the mentioned White Rock from DPPt [It also backs up the idea that Kanto will make a return]. Overall, things are tying together nicely and a lot of questions are starting to be answered. I mean simply be piecing together some parts of the loose ends you do eventually get answers. So, this video of the confirmed events was definitely beneficial to see.
Edit: Nice translations, I can definitely see it all play through quite well. GameFreak and Nintendo has made something both beneficial to themselves and the fans once more. Also, you are welcome,for the link.
