From what I understand LPDDR4 as part of Cannon Lake is directly affected by this delay.
Do we have confirmation of this? It seems startling to release yet another generation of laptop CPUs without this... but I admit I can’t find anything to to the contrary.
Pretty much anyone building mid-to-high-end laptops must be livid.
Coffe Lake does not support LPDDR4. Cannon Lake do support LPDDR4 but is now delayed. As a matter of fact I am wondering if they might skip Cannonlake and go Icelake instead.
There is no other rumoured "lake" in between, so yes, another generation without 32GB RAM Laptop.
These information are widely available everywhere, not sure what you want as confirmation.
The linked article mentions “Whiskey Lake” as an intermediate 14nm range (actually it says “desktop”, but I’ve seen it mentioned in a laptop context elsewhere). But I fear you’re right that LPDDR4 support is still being left for Coffee Lake...

Well those which put a premium on sleep/suspend autonomy, which for DDR4 is the big edge of LP. IIRC the "active" energy consumption of DDR4 was lowered to LP-level already.

They use regular DDR4, talking about "desktop" RAM may not be the best for comprehension, DDR4 is available as SODIMM module and lots of work went into making DDR4 significantly less power-hungry than DDR3.

IIRC it would burn battery ~30% faster when sleeping (e.g. when you close the lid, unless you have changed the configuration to be strictly "suspend to disk", which requires going through pmset and the command-line).
