Personally I wouldn't say it's been going as badly as yourself and the YouTube videos you presented have made out. Admittedly I don't play more than 4 hours of Call of Duty a week, but in that limited timeframe I've been rather happy with the things they've brought out.
As far as I'm concerned I'm getting plenty of new content to enjoy, so much so that I haven't come close to unlocking all of the guns yet, and I'm still getting used to the new maps too!
