For reference, Zhuge tweeted that PS4 had 140 games in development as of June 2013, while Switch has 80 right now. Seems quite decent in that perspective, though nothing spectacular.
I really need a more concrete layout of the launch period and window before deciding to buy. Zelda is a great game, but I would like something more.
The presentation seemed really weak to me, with very few games of significant weight seeming to exist for the first few months. That is disappointing, and makes the 300 (likely) price point a tough pill to swallow. I find it hard to believe that there was so much focus on motion controls, I had hoped they would be done after Wii, but it seems they want to try again with the same idea, and that is disappointing.
All in all, I had hoped for more from this presentation, especially from western third parties. I don't really see the appeal at this moment, but maybe if Zelda and Skyrim arrive at launch I will consider it.
