Considering TES started on PC and they have the most knowledge with PC, it being harder to patch PC is a complete load of crap. Stop kidding yourself.
While you may be correct about the patch itself not being more difficult, would you care to visualize the test process for the different platforms and rethink you stance. PS3 and X360 are SET peices of hardware that (theoretically) only require a single test platform each. How many differnt test platforms would you consider "enough" when testing the PC version? 5, 25, 100, 500? Stop kidding YOURSELF.
Nothing in that quote implies the PC version is just sitting there waiting for the console versions to be verified to get released. In fact, I'm guessing a much more difficult and lengthy test process is being done on the PC version as there is no outside verification to be performed like MS and SONY appear to do.
If they said it was going to be released tomorrow, someone would comlain that they didn't get it yesterday.....
