Playstation Blog just posted this teaser, which reveals the date 20/2. (I just realized you yanks might not understand the date: it's February 20th)
Is it, asthinks, just a red herring? Or an official PS4 reveal?
Edit with personal thoughts:
So just a week or so ago the CEO of Sony Kaz Hirai said that they were waiting for Microsoft to make the first move before talking about Orbis for realsies. Was that just him talking out of his ass? Or was it a ruse? For all we know, this might not even be an Orbis-related announcement (which will boil the blood of a lot of people, I imagine). Speaking of Microsoft, how will they react to this? Can we expect an announcement from them on February 19th? Will they remain silent until E3? Or hold their own event soon after Sony's? It's fun to follow these things, and I'm looking forward to February 20th with excitement. Either Internet will go up in flames because Sony won't mention Orbis, or Internet will go nuts debating over the newly announced console. Fun stuff!
