Just a thought, be does anyone else think it was a bad idea to keep both the gauntlet and the tesseract on Asgard? I mean I assume that post credit scene was meant to be Thanos in Odin's weapons vault, which probably means he's already made his move on Loki and Thor will likely be returning to his home in ruins again. That's assuming of course that scene is happening "now".
So that makes four of the six stones accounted for (space, power, mind and did they ever confirm if the Either was the soul or reality gem?) I'm assuming the other two (time and either soul or reality) will turn up in 'Doctor Strange' & 'Captain Marvel'.
I can't believe it just now occurs to me, but with the Infinity War split into two parts a year apart, does that mean the war will be ongoing across the MCU for a whole year? Suddenly Captain Marvel 7 the Inhumans movies being smack in the middle of that makes a whole lot of sense.
I wonder how that'll effect AoS, if it's still on the air in three to four years?
My reading on Ultron is that he took the line "peace on Earth" a tad more literally that it was intended.
Not sure it can be seriously claimed that he's from Chitauri technology. Pretty sure that's just something they put out there to obscure the face that yes, the sceptre did indeed contain the mind gem.
Speaking of, I liked how they showed that the gem itself contained an actual mind. I wonder if there's a long term plan for that? If it weren't for the rights issues my top two guesses would be Galactus or the Phoenix.
However i don't see a connection with Galactus or Phoenix as they are galactic forces of their own, separate from the Infinity stones (at least in the comics). Since both Galactus and Phoenix are IP's that Marvel has licensed outside (Galactus belongs to the FF license and Phoenix belongs to the X-Men license) it is very unlikely that Marvel can use them.
The only reason I suggested those two at all is because they're the only ridiculously powerful and destructive cosmic beings in the Marvel universe that I'm aware of (though I'm far from well read in such things!) But like I said, the right issues probably put them both off limits.
A shame because I think the Phoenix would have suited it quite well, being a more elemental cosmic force than an actual character and that it already is associated with a (admittedly non-infinity) gemstone in the comics. It wouldn't be too much of a leap to make the mind stone and the m'kraan crystal one and the same. Much like the cosmic cube and the tesseract seem to have been merged into one thing for the MCU.
Also, the mind crystal was yellow, which would seem appropriate, no?
