Well, it would increase speed to a certain degree: The theoretical max speed would only be used after you've taken more than four shots (since one pic is only written to one card, but I agree, it's mostly only then more speed is needed), and even then resulting in a top speed of 4x max card speed. If the bus is upgraded to the max and using top-performance cards it would still result in a max speed of 4*90mb/s=360mb/s, which is only a bit more than about half of the max data production rate for the K1 and the buffer could still fill up. Sure we could add 8 cards then instead to write faster than you can shoot but with 8 cards it starts getting ridiculous =), that's why I favored the SSD - you get those speeds with a couple of storage chips.
So I agree 4 cards would be a (large?) improvement over today (aside from somewhat more hassle when offloading 4 cards since many here seems to prefer that way to offload the data), but for my part I'd still prefer an SSD-version due to the advantages I mentioned above, unlimited buffer, and if paired with usb 3.1 or later, it could be read/offloaded at 1Gb/s, while the cards would still have the max 4*90mb/s and/or having to eject 4 of them depending on the camera bus speed or prefering to offload by cardreader.
