Very unlikely in my opinion. The economic barrier to entry to bootstrapping a mobile ecosystem appear to be so high that extremely well funded efforts have floundered, I see very little reason why Sailfish will succeed where others have failed. List of failed efforts to jumpstart mobile ecosystems are - Creative (ziilabs), Microsoft (multiple efforts), Blackberry, Nokia (Maemo and Symbian), Ubuntu (Ubuntu phone).
