i would argue the opposite. almost no one is releasing the newer versions of SSDs (with the faster controllers) in PATA-ZIF. Only time will tell if we can find a SATA-LIF solution, but the faster Sandisk SSDs are definitely 5mm and definitely not PATA-ZIF.
Yes, this one is correct.
PATA-ZIF is done.
However, I highly doubt we'll see SATA-LIF solution because MBA is currently the only vendor with this in their ultraportable. Not enough demand.
At least the PATA-ZIF solution was more common.
