Seriously, 4th gen was just announced.. Most vendors will not have a "flagship" offering ready for 3-6 months (some maybe later).
If you can't wait, Apple and Sony seem to have units available now (or soonish). Acer, Apple, Dell, HP, Lenovo, Razr, Sony, Samsung, and Toshiba have all announced laptops with 11-15", touchscreens, all supporting 4th Gen; possibly more, but those are the ones I'm aware of, at any rate..
I only say "flagship" because I think you're pipe-dream features are only for a niche market.
