Next gen processors

so i am not the smartest kid on the block so i am asking you guys about this , so later on i've head that next gen core i7 extreme processors will allow to have a extra full pci slot ( unlike the ones in between )
so basically allowing a 4 way sli with a pci ssd or some other card or some dual slot card

so does this in 2014 q4 there will be boards with 5 pci slots and there will be new bigger cabinets according to this size , i am in deep thought of buying a new coller master cosmos 2 and also a massive upgrade to maxwell and new i7 extreme one , if i get cosmos now would't this make the upgrade to next gen boards impossible o_0 please help me out on this one

 

The new chips will have more PCIe lanes than the mainstream models, 40 vs 16, which would allow x8 x 5 directly by the CPU. However, the most common form-factors for X99 will still be ATX and CEB. I doubt we'll see an XL-ATX board, that kinda fizzled out years ago. Now with PCI Express and M.2 one can have PCIe based storage and leave the slots open for 4 dual-width cards.

 

If this is true, you'll need a case like the Corsair 900D, which has 10 expansion slots and fits Mini ITX, Micro ATX, ATX, E-ATX, XL-ATX, and HPTX motherboards. There aren't many cases this big, and this one is considered the best for the price, ($320). That's nothing compared to what you'll spend on 5 video cards and the power supply to run them (only a few of the top 1500-1600 watt PSUs have 10 PCIe power connectors, $350 to $450, and of course you'll want 5 GTX 780s or R9-290x, that's another $2500. The mobo will be $400-$600 as well. To keep all this hardware from instantly melting down, you'll need an extensive water cooling system, another $1500-$2000. I hope you're saving your pennies (in 55-gallon drums), it's going to take about 700,000 of them...
