CE - I do some part time work (play) for a local culinary store prepping for demonstrations and catering events. I've used, and still use the knives you expressed interest in above. Some considerations that may not be obvious include:
Most retail customers do not want to spend the time or invest in sharpening equipment. They bring knives in maybe once a year to be sharpened on a pull thru grinder set at 20 degrees. Its a serviceable edge that probably makes more sense for them than buying sharpening equipment that does not get used.
The wusthof slicer you linked will slice thin but the wavy blade will has little torsion strength and will bend, tear, chip easily. Its not suitable for anything with a bone in it. The blade is not serrated but is not straight either. It will not lend itself to sharpening or any sort of repair.
The Shun carver I've used is duller than an Al Gore speech. Shun recommends that their knives be returned to them for sharpening. The retail part of the store sells Shuns but will not accept them for sharpening. Before considering further you should ask your local WS if they will sharpen the knife. (Ask them about 15 degrees as well but be prepared for a blank stare.) To you this means sending the knife off periodically for approx a month to maintain the edge.
The Japanes knives described above would be very good initially but more difficult to maintain. Suggest you also consider wusthof ikon classic 9 inch carving or messermeister meridian elite carver.
The wustoff ikon line is about 25% higher than the classic line, money well spent as the semi bolster will allow sharpening the full blade and the handle is a little nicer. The messermeister is also semi bolster and cheaper. They are not as delicate as the slicer you linked but are not bone crushers either. Either can be adequately sharpened locally. Dings can be ground out by someone that knows what they are doing - including several here.
Also suggest you consider a cheap cleaver for whacking grilled chickens and ribs as well as chopping brisket. They are not pretty but will do the heavy lifting.
