Anyone remember "Immedia", Quark's flop at attacking the web market?
Those shoemakers at Quark should "stick to their last" first --- polish up and upgrade the product to make it more useful and compatible for their core clients, the print professionals. The multiple undos, layer and transparency features are now standard in just about every Adobe or Macromedia product, so it's critical that Quark support them.
There's no doubt that many catalog pages and other print materials eventually have to be re-purposed for the web, but usually the design parameters are completely different, and a web page doesn't necessarily work well in print or vice-versa (just print a few web pages or spend an afternoon reading pdf's on your screen to get the gist of what I mean).
Once people have the option of linking html or web-based images to their Quark print documents, you can just image how much fun the service bureaus are going to have outputting films and plates (fonts, size of type, resolution, RGB and other color space issues, broken links, etc).
