Eurogamer's latest Witcher 3 write-up veils an intriguing little snippet about the future of Xbox One, care of CD Projekt's lead engine programmer Balázs Török. According to Török, Microsoft gradually "opened up" ways of getting "more" out of the Xbox 360 across 2007 and 2008, and this may be the case with Xbox One, too.
"On the PS4 it's very good to have the fast memory," said Balázs Török, "everyone is really happy about that - but the problem is the game has to function on everything.
"No we are not holding it back," he added, "it's just we are not at the stage right now to go in and optimise on each platform specifically. We want to make the game and the whole engine run on everything, with all the features and bells and whistles, and then just optimise, optimise, optimise.
"I don't see a major power difference. The memory is very different but I already said that before. Pure computation power, if you just measure that, there's no major difference."
"The Xbox One is pretty easy to understand because not just the hardware is similar to the PC, but everything like the SDK, the API is really similar to what you would find on a PC. On PS4 this is a little bit more complicated, but I personally worked on PS3 before.
Balázs Török did flag up one unusual thing about the Xbox 360 from around 2007/2008, though.
"I saw how Microsoft opened up certain parts that they hid before from developers," he said. "They opened them up, like, 'OK now you can have this back door, and it's risky but you can do this and that...' This is how developers learned a little bit more and more every step. From Microsoft it was a good way to do it to always let the developers do a little bit more."
Does he think Microsoft will do the same with Xbox One?
"I don't know because we are not at the stage where they would open up something new," he answered. "We have what we have right now, and maybe we will have some more low-level access in the future.
"It's not like they would open up new hardware or anything - there's nothing new in there. It's new ways to do something. Both companies are already using all the knowledge they have from previous products to make the API tailored to games ... so I expect that they will do something like, 'OK now you can do this; it's extremely risky - only do this if you know what you're doing! But you can do this.'
"It will happen, eventually, but right now we are preparing for it."
