We dropped in to visit the folks at Acer and have a look at the Iconia A700, and it's impressive. The first thing you notice is how thin and light it is (9.9mm and 600grams, respectively), and then you turn it on. The 1920 x 1200 resolution will absolutely blow you away, and the quad-core NVIDIA Tegra 3 inside pushes all those pixels nice and smoothly.
Acer's also made the A700 a complete media center. You have HDMI out, as well as HDMI to VGA support so you can use a projector, and the microUSB port supports USB host mode so you can connect things like your camera through the included micro to full size USB adapter. Now the switch to MHL in Ice Cream Sandwich (which the A700 ships with -- no "update soon" nonsense here) makes more sense. Add in features like Dolby Mobile 5.1 HD audio output and a microSD card slot, and this looks like one of the tablets to buy in 2012.
