There has been some talks already about the successor devices of still hot selling iPhone 6 and 6 Plus. Those talks involve the anticipated specs.
The latest just announced leak by @leakfly suggest that both upcoming successor devices by Apple will finally feature 2GB of LDDR4 type RAM memory. That is the double amount to what we are already used to seeing on Apple devices. It seems that Apple is ready to increase the memory on their devices.
Yet, it will be one more “as twice as fast” announcement on the stage as Apple will definitely announce the upgraded chip inside, which will again be a “major step” since last generation.
