They used the word 'commit' in relation to the 50% i'm pretty sure.  Obviously we could end up in some nuclear war in the next 6 months, and yeah, they might have to rethink that, just like most 'commitments'.  Not sure what forward looking statement could be a commitment by your definition.

Lots could happen that would put buybacks on hold: 
  
 - The memory market could soften faster than expected 
  
 - New capital investments might be required or new opportunities arise 
  
 - The trade war could impact MU more severely than expected 
  
 - Chinese market entry could be faster than expected and force MU to react/respond
