I think he might. If the Phillies were out of the race, I could see Little sitting him a few times to 'preserve his health down the stretch' (i.e. keep from breaking a dubious record a la Jose Hernandez with the Brewers), but considering the fact that Philly is within a game or so of the WC, Howard will definitely 1) get every possible AB, and 2) get pitched to by opposing teams (theoretically).
