2008 could be the doom of PS3. But that's not yet decided. I think a more appropriate premptive term would be is it's the Deciding Year for PS3. If PS3 continues sales like it did in 2007, in 2008, then it'll make it impossible to catch Wii. If it turns it up and starts at least outselling Wii a little bit then there is a brighter future. Remember to gain on someone, you have to sell more them. Meaning simply not being outsold by as much doesn't cut it.
IN 2008 PS3 will have to make gains on the Wii, not smaller setbacks. Meaning Sony needs to focus on that Europe/Other market, which apparently still has a good Playstaion brandname there. A good 35% of the market but they need to focus on UK and France which happen to be their weakest markets, and ironically the largest individual markets in those areas.
Secondly they need to see if they can catch Nintendo why they are in a lull in Japan. They've tried with the 40gb but it hasn't really seen a mass effect yet. Nor has it really affected the Wii at all. If they don't do anything, then Nintendo having the more popular brandname, will simply come back up when it comes out of its self created lull.
But its the American market that I think we should all be seeing where PS3 needs to make the most ground. It's in 3rd place there, and really not showing any signs of coming out of it. Nor really making it a close 3rd place, like GC did with Xbox there. Sony has to makeup ground in America next year. It's 50% of the market. If they don't and suffere another 3rd place year there in 2008, then it's looking like a gloomy generation.
Although percentages are in majority favor of spelling DOOM for PS3 in 2008, that is not officially decided yet. These rises late in the year, although mostly attributed to holiday season, still have risen and could have been because of new prices and SKU's. That will be determined early next year. So I don't think we can say it'll have a tougher year, but like Sony, you need to know what PS3 needs to start doing. And that's GAIN ground in 2008, not lose ground(even if not as much). You can't say PS3 is gaining on Wii, technically til it outsells it for a week worldwide, something it hasn't done, since its launch in Europe. This is what PS3 needs to do. Some see it as a longshot. Some see it as plausible. Some see it as impossible. I simply see it as a possibility but not a strong one.
