Copy-pasted from before E3, and borne out entirely by the conference events and their aftermath on these forums:
It depends what you mean by 'Win E3'. If you mean who will have the best games regardless of sales potential then it will be entirely subjective and in the vast majority of cases confirmation bias will ensure that everyone who expected/wanted their preferred company to win, will believe they won. This is especially true where niche titles such as the Last Guardian could be shown, leading fans of such games feeling as though a certain company 'won' E3.
If you mean who will best leverage 'E3' as an opportunity to promote future console sales, this is almost certainly going to be Microsoft of Nintendo. Quite simple, this is because Sony is currently outselling those two companies, often combined, despite an almost complete lack of high-budget, high visibility AAA content. In other words, the only place Sony has to go at this E3 is down. Whereas even a viable attempt at levelling the playing field would represent an E3 'won' for Microsoft or Nintendo.
If you mean on these forums? It will go by userbase - in line with the aforementioned confirmation bias. Sony > Nintendo > Microsoft - irrespective of what is actually shown.
