I don't think there will ever be true parity, but I think there will be some merge.

For example the old part of Denver (Downtown, LoDo, RiNo, Ballpark, Five Points, Curtis Park, Auraria campus) is laid out in a grid that is positioned perfectly diagonal to the four cardinal directions, and most of the rest of the city is laid out in a perfect N/S, E/W pattern. 

We're talking new roof, new electrical (wiring too, not just box), new AC, new kitchen with granite, stainless, porcelain at a diagonal, serious landscaping.

The diagonal, chocolate brown siding was not in bad shape, but it was just a very dated look.

Me and my wife cant decide on going with diagonal  vs straight wood floor.

There were diagonal cracks throughout most of the walls in each room, and in the basement one of the exterior walls had like a 1-1 1/2 foot crack in the block starting at the floor and there was a small ammount of water running from that to the middle of the room.

Would the partner's agree to a 60/40 net income split to get parity in after tax income?  

The neighbors fence starts in the ally and runs diagonal straight into the corner of my house.

The EU is going to fail as the Euro was drawing near parity with the Dollar in January after a long slide down from the High in May of 2014.

There is residential diagonally cross the intersection so perhaps that would help.
