I'd also like to voice my support for this. 64GB in the P570WM (or any portable/battery powered workstation for that matter) would greatly help the engineering students at the university that I work for. They have a number of CAD models that require at least 48GB to fully load the model into RAM without swapping to disk. They also often go on road trips for student competitions where it would be extremely useful to have such a workstation with them. If it's possible to make this happen, myself and the students would be extremely grateful!
