Lense selection

[Eduardosalda]

Hello. I have a Canon Mark 5D II with the following lenses: 50 mm, 70 -200 mm, and 85 mm. I want to purchase a new but i have dounts on what lens to buy. I've looking at the 24-70 L and 24-105 L. Whch one to buy?
I don't know if Canon will replace one of these leneses, so it's better to waiit until the nee version.

Thanls
