Apple to announce new high-speed connector for Macs, report claims

Anything that fast has to be optical fiber. Nice touch.
But at least until such might become industry standard, it would more likely to supplement, not supplant, currently supported connection mechanisms.
If Apple tried to run that way exclusively, I suspect that its market share might drop like a rock in a vacuum.

Intel to debut Light Peak alongside Apple's new MacBook Pros Thursday

Yikes, that "do not open" bit plus "significant feature enhancements" does imply the new MBPs might come with LightPeak.

That would be quite amazing.
But when will peripherals come with that connector?

I understand the LightPeak concept, well sorta, but with a LightPeak output, does that mean all new devices must also have/accommodate LightPeak input, and will we all need new cables or adaptors?

Also, will there be several LightPeak outputs or must the peripherals be daisy chained or some such?

speculating wildly... new computers come with the usual ports plus lightpeak modified magsafes. The brick is a little larger, and has ports ON it in addition to plugging into the wall. So you plug your monitor into the power brick, with its displayport, usb, firewire maybe. (or maybe not!) and maybe sound. Then when you come home with the computer, pop in the power cord and it's all there. It's like a dock, but one easy connector instead of a big dock.

But that's just my dreaming...

And they announced this on a Thursday.
[as opposed to a Tuesday, which is almost exclusively the case]

Now, I wonder if I will be able to add Thunderbolt to my Mac Pro via a PCI Express card. Time will tell.

very likely. but right now they are adding ports. ports must be on computers before peripherals will start cropping up. So it'll be at least a year before we see any variety of thunderbolt peripherals.

(and expresscards for those of us with MBPs would be nice too)

From what i've read, a TB-equipped peripheral would also be able to function when plugged into a USB-3 port on a computer. So that should speed up the adoption rate (on the peripheral side of things).

[<cough> Yes, it seems "TB" is what folks are using to abbreviate Thunderbolt. <cough>]

I suppose one way to get TB, is to use his machine within 30 minutes of going swimming...
