My sales prediction: It'll sell lower than Wii U in it's first week but still competitive, dropping to current Wii U-level sales over the next month.

Price at around $450.

World Wide launch November 16th, 20 years to the day after the formation of SCE.

Launch prices will be $429 and $499. First party launch games are Killzone, DriveClub, and Knack. It will sell out for a few months. Sounds good?

12+ million 1st week. world wide.
$399 USD

Knack is the kinda game that won't sell a lot in the first months but will have LONG legs and will keep on selling (If it gets good reviews).

Plus, being the only "kiddy" game at launch really helps it.

It will release worldwide in November. Europe won't have to wait, although there could be a delay of a week or two. Japan will get it first no doubt.

How many units are sold really depends on how many consoles Sony will be able to produce. I'm predicting that the PS4 will be sold out through the entire holidays. Sales numbers should be around 1 Million in the first week (all regions) and I think about 5 Million till the end of 2013.

As launch games I think we will see Killzone, Drive Club, Uncharted 4 or a new IP from Naughty Dog and probably The Last Guardian. Bettlefield 4 should also make an appearance as well as sports titles by EA. Other than that, I have no idea so far. But I think we will see more than 20 games at launch, half of them exclusive.

And that would be my first prediction at vgchartz, yai. :P

Price - £350-380 and £400-£430 for the 2 different storages 

Release - Japan and US November 28th, Europe late 2013/early 2014

Sales - between 300-400k (first week)

Hmmm, 1 million first week, more if Europe isn't delayed, almost 10 million first year. I expect a decent marketing push and hype. Price, rumored $349(if someone is right) or $429/$529. I believe it will just be solid $399/$499 for marketing reasons, pleasant to the eye, doesn't match Nintendo. Launch games 20+, some big name titles from respectable devs, several last gen up ports/down ports. Praised as one of the best launch line ups.

November launch. WW.
Price: 2 SKUs, one at 399, other at 449
Sales: 700K first week
Not sure about holidays and black friday, possible supply problems.
January 2014: sales over 100K/week without releases, boost when new games launch.

1 million first week without even launching in europe? HOLY JESUS!! The PS4 will make the PS2 look like a Dreamcast if you're right.

I hope so, I think PS4 will enter in on a good note this time and if the price is right then I might be close. Their new marketing team might really do a number. With Europe I'm expecting it to top Vita first week of 1.1 million by a bit.
