It's true. It could be a matter of, with the shrinking of the immediate royal family, combined with the age of his grandparents, that he and William will have to take on more of a full-time role (William more than Harry which is why Harry isn't leaving the military entirely). Maybe his relationship with Cressida is a factor as well as well as his desired wish to work more on some of the charities he's involved with? This gives him the military career, helping the RF, helping his personal life and charitable endeavors. It takes him out of the active role he seems to like but it could be a trade-off he's willing to make.
From CNN: "Prince Harry is ending his time with Britain's Army Air Corps and is taking a staff officer role in London, Kensington Palace announced Friday. The move takes him out of a potential combat role flying Apache helicopters and gives him a desk job in London....The move to a new role comes at a time of increasing British media speculation about his relationship with Cressida Bonas. Harry, who is known as Captain Wales to his fellow servicemen, will keep the same rank in his new position. His responsibilities "will include helping to co-ordinate significant projects and commemorative events involving the Army in London," a Kensington Palace news release said. Prince Harry spent 3½ years in training and operational service with the Apache Force during his time with the Army Air Corps. He was awarded the prize for best co-pilot gunner during training and became a fully operational Apache pilot in February 2012. He qualified as an Apache aircraft commander in July of last year. Lt. Col. Tom de la Rue, Harry's commanding officer in the Army Air Corps, said: "Captain Wales has reached the pinnacle of flying excellence as an Apache pilot, particularly in Afghanistan and, in the process, has proved to be a real inspiration to the many Army Air Corps officers and soldiers who have come to know him so well over the last two years."
Harry has embraced an increasingly public role in the past couple of years. In December, he and a team made up of wounded UK veterans reached the South Pole, after a grueling trek across the Antarctic with the Walking With The Wounded charity.... Harry had won praise from the UK media for embracing a more central public role in support of the Queen in her diamond jubilee year.
This included representing his grandmother at the Olympics Closing Ceremony and on a royal tour to the Caribbean."
