I was able to see the new Technics SL-XP7 at the Summer Consumer
Electronic Show.  They had several working models that we stood in
line to listen to.  They sounded good but the background noise made
any critical listening impossible.  The earphones that they had
them hooked up to were also less than top quality.  

The unit by itself isn't a whole lot smaller that the Sony D-5, but
when you put it in the battery pack case, the total is quite a bit
smaller than a comparable Sony unit.

They call the pickup system the FF1 for fine focus single beam.
This system features the new Technics Accu-Servo System which uses
extensive digital circuits to achieve a superior level of reliability
and accuracy that they claim was a problem with other single beam
systems since the focus error signals and tracking error signals
were derived from the same beam.  This system is supposed to overcome
that problem.

They also tout their friction free 4-wire suspension which is supposed
to resist physical shock better that the Sony unit.  Another feature
is their CCF (combined-collimator focus) lens.  They claim that by
supplementing the objective lens with a collimator function, performance
is improved while reducing the size of the unit.

I like the LCD display a little better that the Sony unit and it is
programmable but I don't know how much of a selling feature that will
prove to be.  I can't imagine a person doing a lot of programming with
buttons this small.

It uses a 16 bit linear decoding scheme and 44.1 Khz sampling frequency
which I imagine means analog brick wall filtering although the man
demonstrating them and answering questions said he didn't think so.

It comes with an AC adaptor and cables to hook up to your home system.
The battery pack is optional.  They claim it is good for 3 hours of
playing time and it takes 8 hours to recharge.

Hope this helps.  Oh, one more thing, they probably won't be available
until late summer or early fall.
