How many times did the author use the word "purported" in that article?
Regarding system memory, there are no excuses why PS4/XboxNext won't use at least 8GB of DDR3. I mean really, you can already find 8GB of DDR3 for $28 CDN this holiday season. By this time next year, at cost, I bet you can get 16GB of DDR3 for $55.

I am not saying 16GB will be in those consoles but not putting 8GB would the biggest cop out ever in terms of costs. We are talking about $30 here for 8GB, which means 4GB is barely a savings of $15.
