"————果たしてソロデビュー15周年を迎えるこの2013年、椎名林檎は何らかのアクションを起こすのだろうか？ 期待は日に日に募るばかりである。"
Which Google Translate (roughly) translates as:
"---- 2013 solo debut this 15th anniversary, I wonder if some Shiina Ringo really take action? Is expected to raise just day by day."
...
Very interesting indeed. Perhaps one of our Jap speakers can do a much better/literal translation of that sentence for us.
