Hodgson will name an enlarged squad of around 30 players for next Wednesday's home friendly against Denmark at Wembley.
While much of the talk has been of a possible inclusion for the likes of Luke Shaw, Wilfried Zaha and Raheem Sterling, Hodgson acknowledges he cannot put all his faith in relatively untested youngsters for the World Cup.
"We can't just throw every senior player aside because maybe in 2016 there will be even more youngsters coming through," the England manager said recently after the Euro 2016 qualifying draw.
"But we always want to make certain that we do select some young players."
Shaw has been widely tipped to be called up for the friendly against Denmark.
Given that Ashley Cole has not been playing regular first-team football, Shaw's call-up may come at the expense of the Chelsea left-back.
West Ham striker Andy Carroll and West Brom goalkeeper Ben Foster are fit again following long lay-offs.
Whoever is called up, they will be given a taste of what to expect if they make the plane to Brazil as Hodgson is hoping to relay some of the plans he has made as a result of his fact-finding trip to South America last week.
"Even though the focus is on Denmark we also want to introduce some ideas to the players that we have with regard to going to Brazil, about how we are going to do things logistically," Hodgson added.
The Football Association has confirmed that there will be a minute's applause before kick-off next Wednesday for former England international Sir Tom Finney, who died on February 14.
