• "True exclusives" are games that haven't officially been announced for any other platforms. Some of these are merely timed exclusives, and may come to other systems in the future.
• "Console Exclusives" are games that are only on a single company's consoles (so a Vita or PS3 version wouldn't disqualify a PS4 game, for instance). These games often also have PC versions.
• "Next-gen only" games are ones that will not be available on current-generation home consoles. They may be available for portables or PC, however.
• "Late releases" are games that will already be out on some other platform before they launch on the appropriate next-gen platform.
• "Original IP" is a game not based on an existing game franchise or property from another medium.
• Genre totals may not add up because some games were counted in multiple genres.
• These lists are subject to change, and in fact already look significantly different than they would have a week ago.

• Microsoft has more games that are truly exclusive, but Sony has many more "console exclusives," which mainly overlap with concurrent Vita and PC versions.
• More than half of the launch library for each system overlaps with the other system.
• Most of the PS4's advantage in total games and console exclusives comes from a bevy of independent titles they've been promoting quite heavily, largely from existing PC titles.
• Neither system seems set to have an RPG or platform game at launch.
• Generic shooters and/or action games of various stripes make up roughly half of each system's announced games.

So from a general point of view (and just using this data) when comparing just the PS4 to XBO, the XBO has a better launch line up, but the PS4 has a more optimistic future (as far as content goes)?

Edit: By future I'm referring to the presently announced games that are not set for launch.

"Microsoft has more games that are truly exclusive."

Seems the biggest difference in numbers is Sony has more launch indie games. Otherwise they are almost identical with a slight Xbox One advantage.

So if a game is on Wii U and one of PS4/Xbone do they consider it "next-gen only?" I assume, yes.

Compared to the PS3 launch, the PS4 is golden.

So the Xbox One has the better launch lineup but the PS4 currently has the best mid-to-long-term lineup. Now what remains to be seen is if that PS4 advantage is due to Sony truly having more games coming or Microsoft keeping quiet about its post launch plans.

Doesn't PS4 have 2 MMOs at launch? DCUO and Planetside 2?

He stated some truly exclusive are timed exclusives and PS4 is sharing game with others PlayStation consoles.

2 indie games for launch for each console... tied.
