I don't like it.

I'll wait until FFXV, but if it ends up sucking then I'll wait until KHIII but if KHIII is announced for Wiiu (not likely) then I'll get a Wiiu to play X and Zelda too

Strong and a balanced diet. Possibly the strongest launch for a Playstation system, which generally have ho hum launches.

Where did they say they were announcing 25 exclusives for PS4 at Gamescom? Your link says nothing about that.

Edit - Just realized this was little unclear. I meant to ask where Sony specifically stated this, not the website you linked.

Killzone and BF4 will keep me busy but honestly not much First party games coming out during launch. I'm excited for infamous though.

I'm going to have to go with average. It's whats making me wait on buying the PS4.

Average. Im not really excited for any of them.

I wasn't really impressed honestly. Lot of old ports coming out. Killzone is being milked faster than Mario at this point.
A lack of GTA or any new compellingsoftware/features that isn't on last gen system will hurt sales of both X1 and PS4 but it seems to be more of an issue with PS4 at this point because it just has too many old PC ports and I don't see how taking games that were once completely free to play and adding a charge to them is going to interest a lot of people beyond the Sony core.

When the Wii U launched a lot of people complained about ports
Complained that the same games were on last gen systems
They didn't see that big of an increase

These all also apply to PS4 as well. I cant see it having an impact on one consoles sales and not the other if it is indeed such a big issue as people made it out to be.
Then you have to look at the price aspect of it. In order to be able to do everything on PS4 I can do on Wii U out of the box its going to cost someone over 1k. I don't see many people willing to do that beyond their most faithful

Since we're talking those 3 exclusives.. bad.

Killzone looks like a current gen game in terms of gameplay.
Knack looks boring.
Drive Club has been reported to look very bad and videos make it seem like nothing special.

Now, 3rd party wise, it has a good launch, just like the Xbone. But I can play most of these 3rd party titles on the consoles I already own. Both new consoles have a pretty lacking exclusive launch list imho.

I'm not really a fan of any of those games.

MGS5 will be the first game I will get for PS4, not a single other game interests me at this point on any platform,

Average in terms of exclusives, above average with 3rd party.
