The more little bits of info that seems to be gleaned from various sources about the "lessons learned" it all seems less static than that. Meaning, I think many of us may be taking the whole "port don't build new" mention as the literal mantra behind next-gen when it's likely a much broader strategy than that being referred to.
Just recently found this article and it clearly seems to spell out a key lesson learned from last gen.
"Frankly, we made a couple of mistakes in how we built our technology that was going to build all these games," Gibeau said. "Fortunately, we have a very different approach to technology now with an engine called Frostbite that's tailor-made for next-gen hardware. So we're in really good shape from a technology standpoint, which is where we had our misstep last time." http://www.gamenguide.com/articles/3...l-of-honor.htm
Coupled with a more recent interview where he goes on to say;
"We've always been moving Battlefield well out on the specs because of the huge PC embedded base of that business. And so moving from gen-three to a gen-four is not a huge uptick in cost.
"The other key advantage for us is we've been building those types of titles on Frostbite, which is our proprietary engine. Moving Frostbite up to gen-four was a big task, but once you've done that, you now can do that across multiple titles as long as they're using the Frostbite engine.
"That's been going on over the last year. The early look on some of those products is spectacular. It will be interesting to see how it plays out as it ultimately gets finished."
and this from the same interview;
"Historical transitions have been bumpy for a few reasons. One reason has been that a lot of the companies had too many titles. We had way too many titles in the last transition, and the more titles you have, the more expensive it is to convert them from one generation to the next.
"We're much more focused now. We've got a core group of ten-to-fifteen titles. We'll stage those in terms of the transition and manage those costs through that. Our goal is to keep the cost increase for R&D under $100 million. And some of that will be in this year, some of that in '14, and some in our fiscal year '15. ..." http://www.gamasutra.com/view/news/1...p#.URqwSlpbVpZ
So this seems to suggest that another lesson learned from last gen is to not spread themselves too thin working on as many titles. So all this together seems like the lesson was to still rebuild, not port but do so in a more efficient manner.
This leads strong credence that Kolbe, self listed as the Creative Director for G4 Madden in his OS avatar and his team, are working with an entirely new Frostbite engine for PS4/720, something gamers have been begging for. The only downside to that last interview is that it might be implying that we won't see "gen-4", (told you I didn't pull the term out my arse Spliff
), until next year, to coincide with the NFL season launch window, so that part sucks, if true.
