Gadget Tsuushin (getnews.jp) has made some tongue-in-cheek predictions about what will happen now that the Tokyo Metropolitan legislation restricting sales of certain targeted manga and anime has been passed.

・漫画の電子書籍化が進む。
・裏アニメ、漫画が出回る。
・秋本治（『こち亀』の作者）が皮肉漫画を描く（本人が「両さんがæ®é€šã®ç”Ÿæ´»ã‚’送ることになる」とçºè¨€ï¼‰ã€‚
・上記に続きほかの作者も皮肉漫画を描く。
・ゲーム業界の“CERO”の様な物がアニメ、漫画にも設けられる。何故かそれを審査ãã‚‹ã®ãŒå®˜åƒšå¤©ä¸‹ã‚Šã€‚
・反対デモ運動が行われる。
・角川、集英社などが埼玉、千葉でアニメイãƒãƒ³ãƒˆã‚’開催ãã‚‹ã€‚
・ここぞとばかりに韓流コミック、アニメをゴリ押しãã‚‹å‹•ããŒå‡ºã¦ãã‚‹ã€‚
・石原慎太郎の小説が同人で漫画化。
・アニメ、コミックだけでなく一般ゲーム、アダルトゲームにまで影響が出る
・何故か小説には影響でない。
・法の抜け穴として『ロジャー・ラビット』のような実å†ã¨ã‚¢ãƒ‹ãƒ¡ã®åˆæˆä½œå“ãŒå¤šæ•°ä½œã‚‰ã‚Œã‚‹ã€‚
・出版社とçºè¡Œè€…の住所が都内じゃなくなってる。
・ネットのアニメや漫画も規制される。

Translated:

• Digitization of manga
• Distribution of underground manga and anime
• Osamu Akimoto (author of Kochikame) will write an ironic manga instead (one where according to him, “Ryou-san, the main character in Kochikame, leads an ordinary life”)
• Other manga artist will follow suit
• A new entity similar to CERO for video games will be set up for anime and manga, and for some reason it will provide amakudari jobs for retired officials
• Protest demonstrations will take place
• Kadokawa, Shueisha and the other companies will host anime events in Saitama or Chiba (prefectures near Tokyo)
• Korean comics and animation will gain in popularity
• There will be doujin adaptations of (Tokyo Governor) Shintarou Ishihara’s novels (which are said to be quite raunchy)
• The law will affect not only anime and comics but also regular and 18+ video games
• For some reason, novels are not affected
• In order to circumvent the law, there will be new hybrid productions that combine live photography with anime, similar to the movie Who Framed Roger Rabbit
• Publishers and distributors will move their offices out of Tokyo
• Online anime and manga will also be restricted

Personally I am most amused by the Roger Rabbit suggestion. It may just be crazy enough to work.
