Well seeing how Sony has announced their intent to live stream the meeting on Feb 20, I would be very surprised if it is not the PS4.

I see a lot of people citing Sony PS3 support as a reason they won't announce PS4 soon. Sony keeps their old systems going long after the new ones are out. PS3 still hasn't even reached $200 and is still doing 100k per week. It'll get spikes with the big software coming the next couple months and then get up to 120k or so at least when it hits $200 (this is a very conservative prediction as that is a BIG price point to reach).

if it aint ps4 prepare for a worse *Nintendo announce bayonetta 2 exclusive* internet breakout lol

Regardless of any sources or the wallstreet journal, or w/e, the video speaks for itself. Sony doesn't really have a habit of releasing things like that, and unless Sony is completely unaware of what gamers are talking about (which isn't totally impossible) they should be well aware of how people will interpret "the future of playstation". If Sony doesn't announce the PS4, they'll piss a lot of people off and effectively antihype their new system.

The teaser looks way too hype to be anything but the PS4. I doubt Sony would be so stupid to raise hopes like that.

I'm surprised I haven't seen any suggestions of a Vita redesign/price cut announcement.

Dude..again..stop worrying. It's the PS4

Considering the last Playstation meeting they had was to announce the Vita, this definitely is for the PS4. Plus, if it wasn't, Sony would have been real quick to nip those rumors in the bud. Otherwise, it would be a HUGE letdown, and probably the butt of many a joke, if everyone was hyped and then there was no PS4 reveal.

I'll bet my left nut it's the PS4. Just today I got an email from "Playstation" with the link to the video and the caption "be the first to know". I think that's a pretty strong hint.

yep pretty much. I mean they are inviting the 'investors' to this event :D should be a pretty big duh at this point
