Microsoft need to lead in USA by a healthy margin and in other english speaking countries just to keep at the same level, as PS4 dominates everywhere else. As consumers its in all our interests that there is healthy competition. Even ps4 fans must realise without xbone prices will increase and Sony will have less reasons to give consumers value.
However I believe it will be difficult for Microsoft and maintaining a price advantage is critical to success. Personally at this point I'm not interested in either, simply not enough games for me. In Japan its even worse with the ps4 having a poor selection of titles that would be popular in japan so I can't see that improving for a while.
Anyway it will be interesting to see how it all turns out and who wins. Unlike others I can't seem to find any loyalty for a particular brand of console, Yes I like to moan about the wii u's rubbish spec and some of the compromises made in the xbone spec but ultimately at some point in the future I will own all three consoles and enjoy games on all of them (already have wii u). I just hope Microsoft is keeps biting at Sony's ankles and stops a Sony monopoly happening but I fear this generation may go to ps4.
