I thought that was the point of the Virtual Energy, to be between the Gravity Shift and the Virtual Gravity. I think it makes a lot of sense to have 3 balls in each line. A solid, a Hybrid (or particle pearl) and a pearl. Based on this, I dont understand retiring the Gravity Shift.
I am waiting on the Perfect Dimension to be released in the US for the same reason, 3 balls in same line with same core and slight differences in cover.
