yah it sucks because I bought a few apps. is there a hardware inside the cam to enable the apps? i've read somewhere that the addition of dual card slots removed the apps capability. i thought it's just a software thing. I hope Alex from Magic Lantern will work on Sony firmware.
I'm not an engineer, but I don't see why the apps would need specific hardware....the sony OS itself is a modified version of android so it should be pretty straight forward to run apps. If anything, with the front-end LSI optimizing the movement of data downstream allowing for better AF, faster buffer, less read noise, etc....you'd think that the newer cameras would be able to run the playmemories apps better than the older models.
