Kobe was just on Sportscenter, he said he wants to get this thing done and over with as soon as possible. He doesn't want it to get worse, and he's very dissapointed about not being able to play ball for however much time it will take to rehab.
May I add that knowing Kobe's Work ethic, he should get healed quite fast. He'll do anything he can to get better...
In case anyone is interested, here is some info on Kobe's injury
(a labrum tear according to ESPN): http://orthopaedics.hss.edu/services/conditions/shoulder/shoulder_joint_tear.asp
3 to 4 months of rehab...given Kobe's great conditioning and his will, he'll probably be back on the shorter end of that scale (e.g. around September).
