SPOILER WARNING! MAY SPOIL THE ENDING!
It appears as though the ending of
Transformers: Age of Extinction will take place at the West Kowloon Waterfront Promenade. In the first video below, the first few minutes involve Mark Wahlberg looking up as a recording of Optimus Prime's voice (Peter Cullen) is played. It's a bit difficult understanding what is being said, but a partial description has been made. You can view that below the video, and if you have better ears than me you can add your transcriptions in the comment section. The other video and images mostly show additional scenes Li Bing Bing and a Hong Kong police force with Michael Wong and Ray Lui, all looking up at the sky.
"There remains a price on my head, and i risk endangering you if i stay. Cade when you find the remaining stones, mark one as my soul. Defend this family Autobots, as they have you, goodbye, don't forget me." - transcribed by primetime073
Thanks to the heads up from Udana Wijesuriya
