One thing for sure is it will not be cheap.  Out of reach for most of us.

So these are SSD drives that are suppose to connect VIA PCI Express slot vs connecting directly to the MB? I dont get it. Are these PCI-E SSD able to run your OS off of? Or are they just for storage? Can you add multiple PCI-E SSD like you would Hardrives?

It's all about bandwidth.  The 8x PCI-e v2 slot is capable of 4GB/s throughput in each direction (8GB/s total combined bandwidth).

Now, it's important to note that the PCI-e v2 8x slot's 4GB/s means Gigabyte per second.  The best SATA3 controllers allow for close to the theoretical maximum of 6Gb/s, meaning Gigabit per second.  1 Gigabyte = 8 Gigabits.  Thus, a 4GB/s transfer rate is actually 5.33 times faster than 6Gb/s -- and that's just in one direction.  The total 8GB/s max. bandwidth of the 8x PCI-e slot is more than 10x the amount of a 6Gb/s SATA3 port.

With this in mind, it's easy to see how the PCI-e SSD cards, which RAID 0 multiple SSD drives, can blow away your typical RAID 0 SSD SATA3 array.

Don't you loose TRIM function when SSD's are put in RAID?

Normally, yes.  But OCZ solved the issue with their new PCI-e SSDs.  According to Anandtech.com, this is done "by hiding the multiple controllers from the operating system and passing on / delegating the TRIM commands as needed."

I suspect that even onboard SATA RAID controllers will eventually follow a similar path to passing TRIM commands.

Yes, they connect directly into a PCI-E slot so as to bypass the sata controller.  They appear to your computer to be just a regular Hard drive, so you can install your OS or do whatever you want with them.  And you can add as many of them as you have free PCI-e slots.  :)

is this the next wave of faster SSD as they are promoting it? Is this something that people will be switching to in a few years as price come down?

it's not so much "the next wave" as it is "the crest of this wave"... Think of it like, you have a typical engine in your car, but someone else spends thousands more to get a super highly tuned engine in his car, outwardly the two use the same technology and principles, but his simply uses today's technology to more and greater effect, but there is a great cost to it. The PCI-e SSD cards are for two possible markets, business who have the potential write off of a business expense and considerably larger budgets than most individuals. And of course super-enthusiasts, who can simply throw money at their interests until they get the best. For the average person however, it's a VERY promising note for what will be common place in say 5 years when such technologies will be considered common-place and almost passe. A 3 Terabyte PCI-e SSD card will one day be like a 3TB hard disk is now, a common storage device, and perhaps one day further still it may even be an integrated component, and a paltry three terabytes will be considered small for a cell phone...
