Too little too late. Consumers have moved on, those small amount of die hard Blackberry fans can't save the company.
Also Blackberry already lost a ton of the business side to Apple and Android. So many companies switched over because Blackberry took so long to catch up. I don't see them all just all of a sudden going back since it's difficult for companies to upgrade computer operating systems let alone switch phones again.
Sorry Blackberry but you took forever to try and get the consumer market back so you let go of the business sector. Too late now to win it all back now. They can definitely stick around but they will never be near the top like they were before.
QFT.
Their footprint is still larger in the enterprise market than you give them credit for and there is a lot of movement towards Blackberry solutions again but they lost the consumer market and it will take nothing short of miracle for them to have any kind of presence there.
