it's down to the small quantities.

yeah. that's if there's only 10 people. but there are 900 people.
if half of them are prepared to pay extra, that's fine... but it means
i now have to get quotes for 450 with 1gb and 450 with 2gb.
that means ONLY an order of 2000 RAM ICs @ 2gb, and ONLY an order of
2000 RAM ICs @ 1gb.
that in turn means that i can't use the supplier i was going to use,
because he has a MOQ of 5000 units.
that in turn pushes the prices up for BOTH SETS OF RAM
also the split production will also be much more expensive per unit
because now there will be TWO SETS OF SETUP AND TEARDOWN COSTS....

that's about 18-24 months out so we have no way of telling.
i was planning to use smartphone-style LPDDR3 x32 RAM ICs. i have a
design of a PCB layout i was just going to *cough* copy the pin
mapping and *cough* oh look! by a happy coincidence if i pull that
SoC out and replace it with a Shakti one it fits perfectly and doesn't
need the PCB layout changing *at all*! wow, isn't that an amazing
... mind you i have to check that it's not a 650-pin monster. i
wanted to keep the shakti m-class processor down to below 450 pins.
heck i *might* be able to get away with adjusting the tracks a
*little* bit (shorter, longer) but DDR3 layout is such a pain it's
worth going to some lengths to avoid redoing layouts.
