Roger Cheng is right. If they had to choose, Blackberry should have launched Q10 first.
Why isn't the keyboard-rocking BlackBerry Q10 out sooner? | Mobile - CNET News
I thing Roger Cheng is "spot on". Rule #1 in business is that even more important than getting new customers, is keeping your existing customers happy. The hard fact is that 90 % of those of us still remaining loyal to Blackberry have QWERTY phones, and the QWERTY is the main reason we have stayed loyal despite the frustrating delays of BB10. And it is way easier, and urgent, to stop the still loyal from leaving, than getting those who left for iPhone/Android back. That is a process which will take years anyway.
To prioritize the product designed for "those who left" ahead of the one designed for "those who stayed and waited" is simply bad business - in any business.
