The Haramain Team has obtained the following information. According to one Saudi newspaper, the following will be the imams that will lead taraweeh in Makkah Insha'Allah:
Sheikh Abdur Rahman As-Sudais Sheikh Saud Ash-Shuraim Sheikh Abdullah Al-Juhany Sheikh Mahir Al-Muaiqily
They will lead in the following order: Night 1 (and all odd days with the exception of last 10 nights): 1st 10 rakaats will be led by Sheikh Saud Ash-Shuraim last 10 Rakaats will be by Sheikh Mahir Al-Muaiqily (we are assuming Sheikh Muaiqily will lead qunoot)
Night 2 (and all even nights with the exception of last 10 nights): 1st 10 Rakaats led by Sheikh Abdur Rahman As-Sudais Last 10 Rakaats led by Sheikh Abdullah Al-Juhany (we are assuming Sheikh Al-Juhany will lead qunoot)
As for Tahajjud Salaat, it will be Sheikh Abdur Rahman Al-Sudais and Sheikh Saud Ash-Shuraim Insha'Allah. And for Khatam ul Quran Dua, it will be Sheikh Abdur Rahman As-Sudais Insha'Allah. Source:
Once again, this is from a Saudi Newspaper; not from us :)
EDIT: According to a different source, the following will be the order:
First Night Sheikh Juhany and Sheikh Sudais (Sheikh Sudais probably doing qunoot)
Second Night Sheikh Shuriam and Sheikh Maahir (Sheikh Mahir probably doing qunoot)
