Agreed, insider knowledge is needed to know the technical details of course, but some of my problem with that particular paragraph I quoted is as much about the viewpoint and language used than anything else. Sure I'm maybe reading more into it than I should but the wording itself feels dismissive regarding other platforms. It portrays a particular attitude, or philosophy if you prefer. - My brain paraphrases it as "Our engine is PC based, we can do everything on PC and port it to whatever without having to bother looking at or testing the other platforms in any great depth" To me that particular paragraph neatly explains FD's apparent lack of interest in the console ports. Of course this is just IMHO and I accept it's a left-field and completely subjective opinion!
One of the explanations put forward for CDPR's Cyberpunk woes (including by Obsidian Ant in his recent vid) is that CDPR started with the PC version as their base target and a view to 'working down' towards the console versions, when the more usual practice for cross-platform developers is to start with the console version and then 'work up' to the PC version. No doubt FD use the same approach as CDPR, as ED was first conceived for PC and the console versions were added later. Put simplistically, their approach is the PC version of ED is the target design, then they cut that version back until it 'works' on consoles. They are likely tied into doing it that way now because that's the way they started, but maybe it still leaves them open to the same sort of problems CDPR had when porting to lesser hardware?
