Robert, I agree. It's said that for about a year. Do I believe what it says? Nope. When I read between the lines, this is how I interpret the statement.
Quark released such bug laden versions of the previous two major releases, they couldn't afford to release a third version of the software with those kinds of problems again for fear of industry backlash. Secondly, it would give Quark the opportunity to gouge customers for a software "upgrade" that really only carbonizes the current version, which should have been released that way to begin, and while fixing some bugs, introduces a host of new ones to be blamed on Apple's OS, requiring a subsequent upgrade of Quark.
That's just my interpretation. Feel free to draw your own conclusions.
