They also doubled (!!!) the SSD speeds, at least according to their slides. Presumably swapping will be much more seamless, so I'm not sure low RAM would be a huge issue for most day to day tasks.
It will still be a problem. The difference in access time between RAM and SSDs is still order of magnitude faster for RAM (10s of micro-seconds vs 10s of nano-seconds). So even if they doubles speeds random access of small data chunks will still choke your performance.
