Pratt has pretty much bet their (commercial) future on the geared fan concept, so I'm sure no effort will be spared in getting it right and working out all the bugs.
The real question is how long will it take, and will the airlines be willing to wait and/or put up with the problems until they get it worked out.
I see Pratt is paying Bombardier to compensate for late C-Series deliveries due to Pratt's inability to deliver new engines on time.
I'd hate to see Pratt pull out of the commercial market and focus entirely on the military side, but if they can't get the issues with their geared fan engines resolved fairly quickly that could easily happen.
