Would it make sense for them to make a 8GB variant as well? 16GB make it very expensive and actually for gaming it's most likely not needed yet.

It looks like one of the card’s headline features, 1TB/sec of memory bandwidth, was only achievable with a 16gb design (basically a doubling of channels/memory over the previous Vega 64 design, with which this card shares many similarities).

Why can't they use 4x2GB and provide the same bandwidth? Or it's some limitation of HBM2?

HBM2 has minimum 4GB in each stack IIRC

yes, apparently. though thry could probably get it done eventually, probably not worth it.
