Confessions of Pain remake news

Many people through Martin Scorsese's The Departed would've featured Brad Pitt because the rights were bought by Brad Pitt's production company Plan B. According to today's Oriental Daily in Hong Kong, Plan B may be interested to repeat its success by buying the remake rights to Andrew Lau and Alan Mak's Confession of Pain.

The question is why? Confession of Pain is part of the murder mystery genre that Hollywood has done over the years. Then again, I haven't seen it yet, so maybe that's why I haven't seen one reason why anyone should buy remake rights for a story Hollywood has probably done before.

Edit: Just realizing that the page will be gone to make way for tomorrow's newspaper, I'll post the original Chinese text that mentions the news here:

畢 彼 特 前 年 買 下 《 無 間 道 》 版 權 拍 成 電 影 《 無 間 道 風 雲 》 ， 此 片 最 近 更 威 盡 美 國 的 「 星 獎 」 ， 據 知 ， 畢 彼 特 食 髓 知 味 ， 對 劉 偉 強 新 作 《 傷 城 》 亦 感 興 趣 ， 記 者 就 傳 聞 向 電 影 公 司 求 證 ， 發 言 人 承 認 確 有 荷 里 活 片 商 斟 洽 《 傷 城 》 版 權 ， 但 就 未 肯 透 露 詳 情 ！
