I'll make this short and sweet:
Keep my Canon 7D as backup and purchase the 5D III?
or
Sell my 7D and purchase the 1DX?
---------------
Also,
Keep my EF 70-200mm IS II and purchase the upcoming 24-70mm II?
or
Sell my 70-200 and purchase all primes (24mm, 50mm, 85mm, 135mm, etc.)?

Background: I'm interested in progressing to professional photography. I'm basically looking to ensure the longevity and versatility of my gear for all types of photography, from sports to landscape to portraiture. I'm still in the amateur phase, but have been progressing fairly rapidly. Any advice is much appreciated.
