There will be two new Jump Anime according to Jump issue #30. Info is provided by Mr. ◆XvcCOpYEZY, who usually provides Jump TOC on Mondays.
・『ジャンプフェスタアニメツアー'05 開催決定!! // Jump Festa Anime Tour '05
今年もやります!! // We'll have this this year again!!
今回アニメになるのは○○と○○だ!! // It'll be ***** and ***** that will become Anime!!
次号必見!!』 // Keep your eyes on the next issue!!
I don't know if he hid the titles or Jump did (probably Jump did), but well, what do you think will be the Anime?
I think Gintama will be an Anime since in one of the page of the same issue, it says
・銀魂『次号、重大発表!』 // Gintama will have an important announcement!
The other one… I kind of want Death Note, but since it's kind of going down now + there are way too much dialog, I don't know...
Or... 2ch people rumors it'll be Black Cat, but it's already announced, so I don't know why there's a need to hide it.
NOTE: They'll be the Anime in Jump Festa, but not the official ones. Though, it's highly possible that those Jump Festa Anime will become official ones.
