I don't think we'll see it straight away though. It's going to be entirely down to how many more PS4s Sony can ship for the first three months. Once the 'demand' factor hits and both companies start producing based on projections, then we'll see that ratio of sales IMO

Has there been any figures released on how many PS4s Sony can manufacture in a month?

Sure, Sony fans shouldn't count out what MS has achieved this past gen, but Xbox fans shouldn't discount what Sony allowed to happen through mismanagement and poorly thought out strategies at the beginning of the current generation.  MS was likely to steal some marketshare last gen regardless.  Their system came out earlier, was easier to develop for (thus allowing for superior multiplats early on) and was $200 cheaper!

On the flipside, Sony made a hard as nails system to develop for, included technologies that inflated the price to $500/600 (!) and came out later.  Sony really lost their momentum the PS1 and 2 gave them, and if it were any other company PS3 should've been their last console.  But they survived on brand strenghth alone for the first couple of years before changing their downward trajectory and focusing on the games.

This coming gen, none of those issues which plagued Sony exist and neither do any of the advantages MS had.  On the surface, MS is more expensive (forcing Kinect on consumers) and less powerful; Sony is the opposite.  In all other regards they pretty much tie (Live is probably the only thing on MS that offers a tangible difference in experience and PSN will do almost everything it does in the coming gen from the sounds of it this side of HBO Go and working with your cable box), so the big issue here is what the casual consumer will prefer.  A $500 nextgen system or one for $400?

Both brands have worldwide appeal, and XBox may slightly edge out PS over here in America (yes the last gen they had a huge advantage, but preorder numbers show the tides are turning...you have to remember the gen before many more people sided with PS2 over XBox, and I'm sure those same people who care about price and accessibility were the flip floppers who are now on the PS4 bandwagon again), but you can't deny that PS crushes XBox as a brand overseas.  With this in mind, I'd have to agree with the people who pick Sony to outsell MS by a good margin, even if it is just an opinion.

Definitely can see this.

The reason I say it could be even and not 1.5 to 1 in America is because it entirely depends on how Sony decide to distribute their shipments. Perhaps this is why we haven't got the Asia launch date yet. Sony could be holding fast to see if those shipments would be better served in America.

Don't underestimate how strong the playstation brand is either like people have been, works both way.

Yes but I'm not the one parading around having a party before they even hit store shelfs.

Party where? You sound awfully bitter and hurt.

No, just laugh at how pathetic this site is at times.

Yes like is an forum, especially gaming forums.

I really do not forsee PS4's America lead lasting very long. M$ has cemented themselves as the dominate brand there and once Xbone's pricepoint is on par with the PS4 and becomes more affordable, it will eventually surpass it's sales. The rest of your predictions however seem pretty spot on (Europe I'd predict 2 to 1).
