Their recent scheduling hasn't been that bad though, excluding delays of course. Uncharted was expected for March and then got delayed into April with Ratchet and now delayed again out of April. I don't think they've done that bad of a job this generation. They've spread their releases somewhat evenly throughout the year, except last holiday.
I mean when you're almost releasing your two big 2016 titles in the same month as Dark Souls you're not doing great with timing. No, I'm not counting The Last Guardian yet, it's not gonna be for real until the week it comes out - and by this point I think it will probably fall by the wayside with how long people have waited and how casual the PS4 market will be by that point.
And now you're delaying into the sake week as Doom, and the same month as Mirror's Edge, so you risk loosing some sales to the niche. They're certainly doing better than 2009-2013 garbage tier Sony with launches but they could try not to risk killing launch windows when they delay their games three times.
For reference, I speak from experience and love when I call 2009-2013 Sony garbage in regards to launching games correctly. I've lived through them killing several games just because they didn't want to put the effort into a correct launch, and we've seen the outcome (dropping the price just to hope games fit into a small jigsaw spot). I'm just glad I can enjoy Uncharted 4 like I wanted to without it having a good chance of killing my favorite franchise.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
