can they up the specs at this point ?
i mean it would be great if they do but is it possible ?
The only logical options is they upgraded it before production actually started...somehow without any of us knowing.
Still the Ram can be debunked... The Overclock is nearly impossible, especially if yield issues (which evidence supports) are a concern. It'd be a different story if they were able to allocate as much or more systems for pre-orders than the PS4. Which is not the case.
Losing more sales to a slight overclock and having another catastrophic failure rate isn't worth it.
Lowering the initial install base even further would result in less support, as developers will start optimizing there PS4 efforts more and more exclusives might be announced the bigger the gap gets. This is a dangerous game, way to close to release.
Short version: Changing the specs this late in the game is a very dangerous game... The risks are to great thus it wouldn't be rational for a corporation.
