The Eye of Agamotto might be, if it's a stone. Or Strange might recover it from Dormammus dimension, but other than that, I agree, it would be a very unlikely coincindence if more infinity stones are on earth.
And we already had one of them discovered in a Cap movie, so I doubt we'll get another one in a Cap movie again, that would be repetitive a little.
