Firstly, does anyone know what's the source text for this?

And Ananda, suppressing his tears, said to the Blessed One: "Who shall teach us when thou art gone?" 
And the Blessed One replied:
"I am not the first Buddha who came upon earth, nor shall I be the last.
In due time another Buddha will arise in the world, a Holy One, a supremely enlightened One, endowed with wisdom in conduct, auspicious, knowing the universe, an incomparable leader of men,
a master of angels and mortals. He will reveal to you the same eternal truths which I have taught you.
He will preach his religion, glorious in its origin, glorious at the climax, and glorious at the goal, in the spirit and in the letter.
He will proclaim a religious life, wholly perfect and pure; such as I now proclaim." 
Ananda said: "How shall we know him?" 
The Blessed One said: "He will be known as Metteyya, which means 'he whose name is kindness.'" 
The only Sutta text that I know which mentions on Metteyya is here
And secondly, this. What do you think of this 'selective spin master'?
