New technologies?
Ask a better question.
A new DVD format will come soon.
The rest will just continue their gradual evolution.
Cache isn’t hardware btw.

Blue-Ray is the newest right now. Blu-ray Discs can hold 25GB/50GB.
While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM rely on a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible with CDs and DVDs through the use of a BD/DVD/CD compatible optical pickup unit. The benefit of using a blue-violet laser (405nm) is that it has a shorter wavelength than a red laser (650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it’s possible to fit more data on the disc even though it’s the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Discs to hold 25GB/50GB.

Motherboards - not a great deal, but PCI-X and PCI-Express slots are relatively new, and important. PCI-X is a standard upgrade slot, while PCI-Express is for graphics cards. Gigabit LAN support is also new, and will be fairly important in future. Its 10 times faster than existing LAN connections.
CPU’s - Dual core processors and 64 bit processors are the newest mainstream technologies to arrive. Some processors have both of these features. 64 bit as yet isnt particularly important, but has the potential to allow for much more complex programs and greater speed. Dual core processors already allow significant speed improvements.
RAM - DDR2 is the newest standard. RAM speeds are constantly increasing, and thats the main change.
CD/DVD ROM - Are both being superseeded by HD-DVD and Blu Ray technology, which, is described in detail above. They simply allow much greater capacity.
Scanners, and Printers - As far as i know, there has been no major advances, merely constant updates and gradual improvement.
Hard Drives - 1.8″ hard drives for portable units have become available which are smaller than other hard drive units. The main new technology in hard drives is “perpendicular recording”, which allows data on the disk surface to be closer together which increases speed and capacity. Its not too common as yet, but it is becoming more widespread. Serial ATA (SATA) is also a relatively recent new connection standard, improving transfer speeds. ‘Hybrid’ hard drives will be available soon that use a large amount of flash memory as a buffer, suppposedly increasing speed.
Floppy disk - nothing new for years, this technology is completely obsolete.
Flash - Is getting bigger, faster and cheaper.
ROM - nothing
Cache - on processors, its simply getting bigger

pci-e bus interface if fairly new, as is the dual core cpu’s
