As you said, everything depends on price and stock of the standalone PS4. If it will be 499$, it will sell like hotcakes, if it will be 549$ or more then it will sell good when standalone PS4 will nowhere to be seen which is possible. If there will be a lot of PS4s in shops then I see people making them their priority over the bundle.
So it is happening...PS4 preorder.
Greatness Awaits!
