I've gotten on this thought train enough times I started doing some digging...
They might need a -little- extra work. Ada 5000 Had 32GB with a 256 bit bus but it's a bit of an outlier... I say it that way because as I did my digging, I'm finding that most boards are 8x16Gb (gigabit) modules resulting in a 256-bit width and 16GB of memory. A 4090 gets to 24GB by going to 384 bit.
Obviously, upping the width would potentially be a redesign, but we can again point to the Ada 5000 as a case where 32GB was done on a 256-bit bus. Might be some extra work somewhere but it's doable.
Even my quoted price is likely giving Intel and/or board partners some margin, unless I'm missing something about DRAM costs and ability to get the densities required. But as it stands, a 16GB A770 is something on the range of 250-300 USD range. A 32GB version for 600$, should actually give them some good margin compared to 16GB a770s.
