Do We Already Know All The Names On The Mitchell Report?

18 months and a gazillion dollars later, the Mitchell Report might not look a whole lot different than Wikipedia's list.
The Mitchell Report will apparently include somewhere between 50 and 60 names of MLB players who did drugs in the last decade. And while that's terrific and all, don't we already know those names? Wikipedia has compiled a list of players linked to steroids/HGH and those who have been suspended. So far 37 players with MLB experience have been suspended and at least 23 have been fairly linked to performance enhancing drugs with varying degrees of evidence. That adds up to 60 players. So my questions remains: If this is all we're getting, who gives a shit?

*Wikipedia's list is actually more complete than this, but I felt it irresponsible to include some large names who have been mentioned in the past but the only evidence available to date has been conjecture. If you'd like to view the entire list for yourself, feel free.
