Yeah, those second-hand "sources" fail to provide any new information or perspective from already leaked information.
I really doubt 25GB/s bandwidth is true.
...
To me vern is the victim of telephone game leaks
64-bit LPDDR4 RAM could still be true as it's based off the Jetson TX1 dev-kit, it's not the exact same situation as when PS4 went from 4GB to 8GB of GDDR5 of the specific GB per chip because 4GB of LPDDR4 RAM is already available.
Parker has 128-bit LPDDR4 RAM which doubled the bandwidth, Nintendo could have opted to do the same as even 3DS has 128-bit RAM but I have no clue if third party developers would have been notified of those details for what's to be expected in the final specs.
Vern's source isn't that reliable at the moment because red flags have been thrown up from Vern saying that Nintendo has secrets that haven't been revealed and that he can't reveal more info yet.
Add to that if he can't get his source verified here, then he should go to a media outlet that he can corroborate or verify his source to see if the rumours have any weight to them.
Vern by "think outside the box" and "very focused" comments do you imply add-ons?
Even that teasing is a bit of a red flag.
