There were rumours, that Prince George would visit the school Eton in the near future.
But this was met with resistance by Duchess Kate. Eton would be too stuffy and upper-crust of an institution for a modern Monarchy... Plus: She, Kate, would miss the little Prince too much, if he went there.

Now the Mirror claims, George will probably go to Marlborough College, which Kate has visited as teenager. On not only him, but later Princess Charlotte too would share this school with him. Another point is, that the College is only a one hour drive from Adelaide Cottage, the home of the Windsors. So Duchess Kate could easily visit her kids.

--------------------------
My take here may sound a bit harsh, but Eton is surely a very good school and I am sure, they go there with the times, to provide the best education possible. And life is hard - especially for little Princes. which are going to become King on day. A clean cut from the parental home in the puberty might be not the worst approach...
