that's a phrase that was used in captian america the first avenger, the tesseract was in norway, hidden in a church, and the red skull said those words, he does not know where it's current whereabouts is, the last time the MCU has placed it was in thors hands at the end of Avengers Assemble, after that we are all speculating

reality stone is also speculation as the collectors museum, had been blown up by karina and the Power stone, as the collector didn't show he stil had possesion of it, means it might be crawling around "Knowhere"

The power stone is with the Nova Corps, on Xandar

The Mind stone is with Vision, (for the moment)

the remains of the last two being the:

Time stone is with the Ancient One

Soul Stone is on Asgard (hence this speculation thread)
