At least one of those insiders were also backing the ESRAM yield/downclock rumour...
.......
And I should explain, this is not really
my rumour, it's eastmen's - now he's a senior member here and his story checks out with me - but I'm repeating it because I've heard some corroboration from other sources (though not on his story that MS is going to devs with a list of changes for feedback on, just that MS seems to be looking at clock increases and that a 12 GB RAM upgrade is possible).
He posted this comment at the end of June which Rangers brought to my attention (his stuff about receiving four PMs is a cover story, he has a proper source):

So, last Tuesday I was asking Richard about his ESRAM article and mentioned eastmen's upclock comment; he initially dismissed it, but then he came back to me saying he might have been 'too hasty' in ruling out an upclock as an 'off hand comment' from a 'rock solid source' of his 'got (him) thinking', so he's chasing it but hasn't heard any more yet.
Now Richard is very skeptical - especially on these kind of forum rumours, so I was quite surprised that he changed his mind after initally ruling it out.
He hasn't heard anything about a RAM upgrade or MS going to devs with a list of upgrades for their consideration though - all these seem unlikely to him.
However, I have one other person with a dev source telling me both the upclock and the 12 GB RAM upgrade are being looked at and are possible.
So make what you will of that - I suppose everyone could be lying to me...
