If Carmack mentioned a new game he was working on every other week people would stop and listen (and it would likely eventually materialize), but with Notch it feels more like "Oh, it's the annual big announcement where he reminds people that he makes games and that he continues to exist.", but the past few of those announcements have been filled with redirected ire (see: Microsoft, fans, the gaming industry, government, money), and the comments are filled with guru-like personal advice replies to fan questions about video games w.r.t. questions that don't call for the advice whatsoever.
All the more power to him if he releases another hit. I happened to think that the personality traits he acquired after his success are at odds with further critical successes.
