True, but at the same time, the industry won't really survive with declining game sales year after year (dammit, trying to find that chart that shows how video game sales declined near the end of the last console cycle). If you want to debate whether those declining sales are really due to the console cycle, or if the new consoles will really boost sales again, that's fine. If you want to argue that the game developers are overweighing the benefits of the new sales compared to the cost of new development, that's fine as well.
But there's definitely a justification for it. I also wish a gaming journalist, or someone who's really knowledgeable would comment on the impact gaming cycles have on brands. For example, will Call of Duty be just as popular on the next gen consoles, or would the new generation give a chance for someone to step in first and offer something? Will players be willing to experiment more with different series at the beginning of a gen?
Anyway, things will be shaken up and change overall, so companies that see themselves going towards inevitable doom would want a new generation.
