hmm, don’t see lots of things there. Only information now. Ghibli has decided not to release a trailer yet. There’s the first official poster and the title logo. The title logo reminded me of “Tonari no Totoro” title logo 🙂
Theme song is being sung by a team of father and daughter.
According to Nausicaa.net here, the second official title will only be release next May. Please go to Nausicaa to read about the recent press conference.
