Higher memory capacities for laptop DDR-4?

[Snowleopard3000]

I am looking at laptops with 4 ram slots (higher end machines). They typically are spec'ed out to take 16gb x 4 or 64gb of DDR-4 memory.

I read that Samsung has improved the process and shrunk the die sizes again for DDR-4 memory. Does this mean that we might see 32gb DDR-4 dimms so laptops with 4 slots can have 128gb of ram installed on them?
