There have been quite a few people recently arguing that the February 20th date will be a disappointment for PlayStatin fans, simply because they believe Sony will not announce a PS4 on that date. But it's looking like a PS4 announcement is more and more likely as analysts argue it will also be happening.
Michael Pachter of Wedbush Securities has said that he is '100% certain' that a PS4 will be announced on February 20th. Game journalists like Adam Sessler also argue that there has been too much hype about this date for there not to be a PS4 announcement. If you piece this together with all the recent specification leaks, and the fact that various sources have been saying the PlayStation 4 would be announced within a few weeks (before the official event was announced), it's looking more and more likely that we aren't just getting our hopes up.
Sony will be live streaming the event as well, so we'll keep you updated on when and where to watch it as soon as we know.
