With statements made by named Atari UK staff, with time/date stamps in terms of the publication, and replies given to consumers question over what happened too, as was with the 5200, i personally fail to see Atari UK spokesperson having an agenda, or the need to track down numerous sources to confirm, as it's pretty cut and dry, 5200 was never released, here's Atari UK's viewpoint, make of it what you will.
The 7800 inital plans saw numerous publications report on, location/venue, planned release date etc, then you had inital speculation why plans changed (Atari couldn't bring it in at a consumer friendly price) and then statements from Atari UK giving their viewpoint, as to why they went with 65XE instead, who'd been involved (at least 2 Atari UK people, who else was handling other aspects of it etc etc) and then to add to that, likes of C+VG's Tony Tak.giving his personal viewpoint on why said plans had changed.
There's a huge gulf between media reports like this and claims by ACE that ex-Imagine coders were working on unspecified 7800 games.That's far too vague.
The fact remains as you well know Greyfox as your 'in' on the GTW Atari article Frank is writing, i conducted an exclusive interview for, spoke to numerous sources about, not EVERYTHING was documented chapter and verse here in UK and sent back to Atari USA, lot of deals were verbal, contracts etc to be signed once games finished.
So a lot has been hidden in plain sight :-)
Whats made me chuckle is when i contact someone who attempts to convert a UK game toan Atari system, game itself is unknown to a lot, people look it up, think, ohh that looks nice, would of been great on Jag, read coders explanation of why it wasn't possible, disbelieve me, until coder posts to confirm, then..claim he lacked experience LMAO.
You've also the incidents where you find a reason a high profile coder never touched an Atari system, from oldinterview he did (easy to find online) and also have someone tweet him to confirm claims made were true, they were, you share info, because it goes agains't claim certain people had made, your public enemy no.1.
Again, cracks me up, i used a mix of search engines on I.E on 360, PS3 web browser, ipad, smart phone, found the info and contacts, never used facebook etc, so why is it so hard to find good research in paid for publications at times?.
