Ninja first thanks for your well developped answer
First,I notice from you links and that confirms my belief is that the growth is not linear but put on paper it might looks like an exponential growth. Usually that spells nothing good and bursts as some points.
We were discussing few days ago with Joker454 and I agreed with his pov I don't expect assets quality to get significantly higher than the quality of AAA games (say BF3 on a good PC).
On average you might be right as not all games are AAA games with 100millions budgets. The problem I see is that average can be a poor representation of reality.
Average could be 20millions for a game whereas there are really few games with that kind of budgets. Like in our society there could be polarization with +60 millions games (speaking of budget) and games with few millions with really few in the middle (cf the 1%). This is already there.
So to me next gen will be even more AAA focused and I don't believe that even a step (not jump) forward in assets quality (vs even PC Silent Buddha) will have a significant impact on the budget of those AAA games. May be percents but nowhere near the exponential growth we saw in the previous years.
So to sum-up for an average game it might be an increase in budget but put bluntly I believe that there won't be that many average games. not proved IP or adventurous concepts may be downgrade instead to downloadable games more often.
I'm not on my computer again tonight. So I can't do proper searches and linking from my phone but somebody on this board but posted some really interesting info on the market evolution ( no growing) and the weight of AAA games in this market (growing share of slightly diminishing volumes) and within those AAA the growing weight of a handful of franchises.
Isn't somebody at Epic said lately that if you're to develop a games a couples millions dollars (I don't remember the exact figure) you might do something wrong. I think he meant either you go AAA and you need way more or either you should consider a different approach for the game (and most likely its mean of distribution digital vs physical).
So starting from there I don't know who made that initial comment but it doesn"t add up that well to me. If it's a AAA devs I don't believe that costs will increase significantly. If he is in between they be using the wrong approach and they are taking too much risks as there is no longer that much of a market for "in between games". Investing say 10 millions on single game may be a good way to good for chapter 11 filling pretty fast ( may be on some casual kinect games but it's risky and I believe only studios part of a bigger ensemble can take that kind of risks. Actually casual games may be cheaper to develop but must require healthy marketing budget to reach its targets so I'm not even sure of this).
For greedy devs it's not my pov and it's a bit improper it's tough to be personal against pretty big corporations.
Ps sorry for the spelling mistakes, I'm going to fix that asap.
And again there was nothing personal but sometime is bothering to take time to post to receive an "unfair" response or something that could be perceived as such.
farewell.
