The problem with Robert Heinlein's "Starship Troopers" is the problem I worry "John Carter" has - being a 'seminal classic' also means that by the time you get to the movies everyone else has already borrowed all the original stuff. Which is why, to my mind, Paul Verhoeven's "Troopers" movie did the only thing you could really DO with the propert after decades of military scifi had picked it's bones clean: Turn Heinlein's quasi-fascist army-fetishism into a scathing - and kind of brilliant - scorched-earth throttling of every bullshit pro-war propaganda flick ever made. I still maintain that, if not for pre-dating the "War On Terror" by many years, it would be the best movie about the "War On Terror" ever made.
So, of course, it's being rebooted.
It would be crazy for them to try and mimic the tone of the first film (or the sequels,) so expect talk of "going back to the source," which will probably also include actually utilizing the "powered robot-suits" that the first film skipped for budgetary reasons. I'm sure it'll result in a serviceable, visually-attractive film... just not one with much going on under the hood.
I could be wrong, of course..
