I think this far into the console race the market share picture has been more or less painted. The Wii is the clear winner with the PS3 and the XBOX360 battling it out for 2nd place. Obviously there is a lot that can change from now until the next gen, but I don't see any major shifts happening. The question is what have the respective companies learned from this round and how to you expect them respond in the next?
PS4: I think Sony thought with the immense strength of the playstation brand coupled with arguably the most powerful hardware they could retain if not increase upon the PS2 fanbase. I also think they are seriously factoring in Blu-ray and controlling the format into the equation, which is worth a lot of money. So I think whilst we generally see the PS3 as a big disappointment in moving from the biggest market share by far to heading for a battle for 2nd, owning the next generation DVD format if successful could turn out in the end to be a greatly profitable move. Regardless of this though I think it can't be doubted that Sony made a number of mistakes including overestimating the hardcore market and its influence and underestimating the casuals.
I expect the PS4 to again play the powerful console card. However, I expect Sony to largely diversify. I think they will still have the hardcore focus, but similar to Nintendo will expand out most likely with assorted controllers that can be bought. This way the hardcore gamers don't have to buy the SonyMote and vice versa. I expect the PS4's online capabilities to be vastly better to rival xbox live. Generally I expect Sony to stay the course and cater to the hardcore but absorb nintendo's casual gamer focus and xbox's online focus.
XBOX3: I think generally Microsoft's plan worked well. They, like almost everyone else, were beaten but the unexpected change in the market to accommodate such a unique device as the Wii. Otherwise though they have successfully increased the quality of their product and their market share nicely. I expect them to stay the course for the XBOX3 but like Sony attempt to expand into the casual gamer market. I think they will also do they alternate controller thing.
Wii2: I expect Nintendo to go crazy. Before this generation they were trying a new concept in uncertain conditions. Now that the concept has been validated I expect them to go all out with the Wii2. Expect all kinds of family and non-traditional games. I think they will try and continue to expand the market and make Nintendo synonymous with games with all these new first time gamers they are getting. They won't abandon their marios and so forth, in fact I expect them to expand upon them with newer franchises. Also now that they are looking in a very good position I think they will invest in a awesome and huge online network with Wii2. I expect the online nature to be highly integrated into the console simply because this is awesome, nintendo is acting very smart these days and they pretty much have the guaranteed market share for the Wii2 to make such an investment worth while.
