Think he never mention anything about himself taking over as the one of the Kings of stuff like that.
Andy Lau's or anyone's vocal is subjective to anyone's liking. Personally, I do not think that Andy is a great singer. Jacky Cheung is the one that wins with both hands down. Again, that is subjective.
Of course, pertaining to the 1-year-promo thingy, I believe his point across is, there is no sincerity in the music industry, especially in the Mandarin music scene.
Take for example, S.H.E. They can cut like, 2 to 3 albums in a year, and guess what, a Best Of S.H.E at the end of the year. Obviously, those are sub-standard productions. Their promo is definitely insufficient, and I need not spell out what and how are they being marketed.
Again, my views are my views. Subjective.
