I happen to know one of the original contributors to the Intel 4004 processor design.  The work he did still exists today in modern processors.  He architected UPS's distribution network in Europe, was a fellow at Cambridge where he was a professor, as well as teaching at several other universities and colleges.  He opened one of the first computer store chains, and still today works on application and system code for companies.

He's not a gamer.  He's buying an Xbox One.  Why?  Because the Xbox One is more powerful than the PS4.

Sure, the PS4 has the specs for the memory, but hidden within those 15 other processors on the APU is a processor that he's excited about and he wants to play with.  The implication is that Microsoft has significantly more in store for the Xbox One than the PS4 could ever hope to achieve.

Look how bad the sales have dropped, 29,000 this past week.

Considering it's like the 7th-8th year of that gen, you'd assume the 360/ps3 would be sold at a profit, or at least a profit with the sale of one game.

But I reckon microsoft tried to play all their cards on xbox one, and in the process abandoning 360.

Xbox One is not selling as much as they would have liked (They wanted to dominate Sony) and xbox 360 has hit hard, likely to get worse as EU slowly abandons it, maybe to current japanese sales levels.

MS have a ton of money, but they still need to make money in each department.

With the xbox one likely being sold at a loss, and recent price cuts meaning they are earning even less, and after the huge investments they made for next gen
(EA love - Dead rising 3/Ryse buyout - Titanfall - Insomniac and $100 million controller r&d) they are losing/not making as much as they'd like money which explains the price cuts & bundling in order to boost sales, very early on.
Add this on top of the fact x360 isn't doing so well for them now, they look like they could be in a nervous position with the xbox division.

The likelyhood of microsoft spinning off the xbox division increases I reckon. 

Look how bad the sales have dropped, 29,000 this past week.

Nonsense. particularly with the recent price cuts and software freebies, they lose roughly $80 per console. The first batches of consoles are always loss leaders, until the (re-)supply chain is "running on autopilot" and generic cost saving measures have been implemented.

Also the X360 Fifa14 bundle is currently selling for around $220 here (includes taxes and store margin, and a $50 XBox store credit), so they are actually losing money on the X360 hardware, too. Might be a country specific thing, though.
