day 1 is a given for any Sony's home console for me :D

Once the system has about 5 exclusives that I want to play I'll consider it. It'll depend on Sony when that is ;)

Will first need to see what MS is bringing to the table and I want to see what uses the touch panel has.

Watch Dogs, Killzone, DriveClub and The witness had me sold.

The trailers and demos for Infamous etc also got my attention.

I see that some people were going to be dissatisfied regardless of what Sony showed, and some the opposite. Regardless, Sony is pulling out all the stops.

I also find it funny that some of you are like "Boring, Generic, Didn't Show anything", when obviously you were watching the Meeting with your eyes closed while going "LALALALALALALA!!!"
Winning factors shown....
-Watch Dogs and Destiny, both Multiplatform but their appearance means they will be right on par if not better on PS4 this go around. Ubisoft and Activision's presence speaks much about the console's standing with them. PS4 will not be second fiddle to MS's willingness to open their check book.

-Killzone Shadow Fall, dem graphics, amazing! Many want to say its CG due to the disparity with KZ2 TECH Demo. I would like to point out that GG did get very close to that level of fidelity with KZ2 and hit it with KZ3. Why this is a mark against them, I will never know.

-Drive Club, a graphics whore's wet dream.

-A "FF" game will assuredly be at Sony's E3. This screams Versus XIII. I was actually hoping they would reveal it there but they have decided to save this Megaton for Later. Regardless, FF is one of the more commanding IPs in gaming. Will be super hyped to see what it is. Also if it is debuting at Sony's conf,and needed to be announced before hand.....probably exclusive.

-Deep Down......looks amazing. The More RPGs the better, and It might be a launch game so count me in.

-Infamous Second Son. I am all about this series, one of my favorites on PS3 (I2's endings are some of the best writing in an action game). Launch Window

-Other games for the more Casual centric crowd like Knack and The Witness.

-Sony says they will not block Used Games

-Cloud gaming integration with Gakai which can lead to some great functionalities.

-Controller actually sounds like a vast improvement from the normal Dualshock without being too costly or alienating fans of the controller(Further spaced Sticks, Share Button, Triggers, Mic jack, Touch Pad, etc)

All of this, while knowing they will assuredly have even more Megatons at E3. In comparison, WiiU showed "nothing new or interesting" when they originally unveiled the WiiU. I distinctly remember the only console exclusive to be shown or even acknowledged to exist was........Nintendoland and Lego City......

So for me, launch Day if I can sum up the cash, if not then definitely within the Window.

If I happen to have around $400 just laying around, then maybe I would. As much as I love PlayStation, I think my PS3 still has a lot to give so i'll more than likely give it a year until some heavy hitter games are released.

That touchpad on the controller sold me for a day 1 purchase, i can only imagine the amazing gameplay possibilities! Uncanny originality and innovation from Sony, paving the way for their return from glory

A reasonable excuse. With The Last of Us, Beyond:TS, Puppeteer, and the plethora of AAA Multiplat titles all hitting PS3 this year, you won't necessarily need a new system just yet.

I am personally waiting to hear more about how this Cloud based BC will work. I usually sell my old console for the new one, which really helps with the cost. I sold both versions of PS2 and a truck load of games +Peripherals way back when, so I got PS3 for like $90. Its not really a game changer for me tho, as if I don't like what I hear I will just keep my PS3.

SideNote: I love how some are bitching about BC, when they never owned a PS3. The PS3's library somehow was never interesting enough for you to buy that system.....but you want to complain about the next system not having that capability. Jesus Christ.....

I think you posted too much sense into one reply!

The main point to take away from Sonys little demo is the backing from major publishers as you rightly point out. This shows that maybe the PS4 will be the core platform to dev on, and port things away from, rather than what happened with the 360 and PS3. It also means that Sony stole pretty much all of Microsofts thunder. Bar EA, Sony had every major publisher on stage announcing games under Sony which is critical in showing how Sony want to deal with this generation of consoles, which seems to be very aggressively.

YES
