Mission replayability

[Kiast]

With the confirmation of mobile phone mission replay it got me wondering,

 

Rockstar had previously told us about the huge amount of open ended-ness of the missions (Heists in particular) but with mission replays, at least in Tbogt, it would put you at the end of the mission cut scene and tell us what to do.

 

Obviously this wont work for something that requires a bunch of planning so I would like to know how you guys would imagine they would work around that, Will they have you replaying it with complete freedom in re-planning or will you be stuck with the same method you used in the first play of a mission.

 

 

 

Personally I would love if each mission replay could be completely different to the next depending on planning, i would love to use a tank as a getaway vehicle
