Depends on what SoC we can source. Not every valid combination of CPU and OneNAND PoP is readily available in low quantities. The higher the number of produced devices, the more likely we can source exactly the SoC we want to use. TI will not even pick up the phone when you call for quantities of 500 OMAP SoC, and with other suppliers it's not much different. So in the end you need to take what you can get.
