It could also just be that....MS is fucking up a lot lately and Sony...isn't?
These insiders have reputations to uphold and they wouldn't risk them over bullshit lies just to keep stories and conversations going. And if not for being so dense, you'd see that there have been confirmations to some of the rumors, such as eSRAM yields possibly impacting # of manufactured units....hence XBO launching in only 13 locations instead of the original 21 (or was it 22?). Just b/c it isn't literally spelled out for you and MS refuses to release an official statement literally saying they're limiting releases due to eSRAM problems, doesn't mean the rumors were false. It's just that unlike a lot of games these days, we actually have to use some logic and context clues to piece and confirm these sort of things together. No one's going to hold your hand for this and if they do, it'll be either sarcastically ('cuz, cmon, you were dense) or well after the fact.
And to the other end, just because you see MS get percentage gains on the eSRAM doesn't suddenly mean eSRAM rumors are false, either. They could've been having the eSRAM issues due to trying to uplock the GPU, and now since they're launching in less countries they have less global system stock and thus less potential bad yields to worry about, so perhaps they could attempt some optimization on the eSRAM and GPU they wouldn't have been able to do before, those optimizations causing dev problems, etc.
Just to take your fears away, not everything is apparently peachy clean w/ PS4 either. All you'd need to do is read
this post. Needless to say however it's not facing nearly as much shit in the can as XBO @tm.
It's not a conspiracy theory if one system happens to be going through a lot of problems and that information is being leaked out. That's just what's happening; don't blame the messengers, blame MS. If they had their shit together the volume of negative XBO news would be miniscule. Reality however is a cruel beast. Just because confirmations of some of these rumors aren't literally spelled out to you in big pastel letters doesn't mean the rumors went unfounded; you are quite literally just being lazy to do some of the detective work yourself, and then get frustrated at the messengers for the wrong reasons. If you can't find it in you to blame MS (or Sony, if they were in this position), then blame yourself.
