This just in: from a press conference held by KT Cordporation, formerly known as Korea Telecom, we learn that the upcoming Samsung Galaxy Note III phablet will carry a Snapdragon 800 chip inside.
The network provider is the first to officially acknowledge the Note III's innards reconfirming that the phablet will offer the powerful quad-core chip.

There's some question whether the initial Note III batch will feature a model with the Exynos 5 Octa 5420 chipset as some sources suggest Samsung is having issues with it. There's also word of a cheaper Note III (http://www.gsmarena.com/cheaper_galaxy_note_iii_with_lcd_and_8mp_cam_is_in_the_works-news-6685.php) with an 8 MP snapper and LCD screen for emerging markets, although it's unclear what SoC will power that one.
The Galaxy Note III is now almost a reality as the September 4 Unpacked 2013 Episode 2 (http://www.gsmarena.com/samsung_schedules_unpacked_2013_episode_2_event_for_september_4-news-6520.php) unveiling nears. There're already a developer units (http://www.gsmarena.com/samsung_galaxy_note_iii_developer_unit_leaks-news-6693.php) in the wild and even release dates (http://www.gsmarena.com/galaxy_note_iii_hits_uk_on_september_16_xperia_z1__september_24-news-6689.php).
