All the back and forth, who likes whom, and who did what to whom between companies is rather worthless blabbering that nobody except consumers really care about. At the end, for multi-national corporations, the only thing that counts is money. Samsung and Apple have been taking each other to court for years now, cursing each other at every possible turn, all the while continuing to mutually sign multi billion dollar contracts. Individuals within these corporations might occasionally harbour actual hatred for a competitor, but individuals rarely have enough power to tump the mighty dollar.
My point is that as long as Android remains the money making OS that keeps on giving, Android and Tizen won't be switching places. However, Samsung does have a responsibility towards their share holders to reduce risk, meaning they must diversify and not place all their eggs in just one basket. That alone is reason enough to keep a backup plan like Tizen around and ready to go. The fact that Tizen can also be used as a weapon to gain a better bargaining position in negotiations with Google is an added benefit.
Although Tizen could be made compatible with Android apps, doing so represents a major problem, as members of the open handset alliance are not permitted to build two types of Android device at the same time. Google forces members to choose between either Google-Android, or any other Android variant, but you aren't allowed to do both. That means if Samsung did go Tizen, they'd be forced to give up on Google-Android compatible devices entirely. That is also a huge risk for a company that makes a huge part of their current profits selling Google-Android compatible devices.
No, despite the tech press dressing up such spats as if they were soap operas for men, Samsung won't risk launching Tizen devices, or at least not Android compatible Tizen devices (compatibility would likely be a requirement for them to succeed), unless they feel they are being cornered and have no other choice.
