The official Pokémon movie blog has updated. Translations of the new entry follows:

Letter Channel #2: A letter from Shun and Ryo

From Shun (6) and Ryo (4), Tokyo
We all go see the Pokémon movies every summer.
We have seen the Pokémon movies three years in a row now.
Last year my little brother went with us.
We are looking forward to this year's movie too!

Shun and Ryo also sent us drawings, thank you very much for those!
They are very good, and you were even able to draw the tiny details on Giratina and Rayquaza!
This year's movie will premiere soon, so look forward to that!

*We added kanji to the submitted text to make it easier to read.
