Bob;
All we can do is wait.
"Mid 2004" is vague at best.
Even the Fall could fit.
I doubt 2005 could though.
I would guess, September or maybe October, but that is just a guess.
That vagary, plus, why would you look forward to another 'buggy' set of
fixes for fixes? It will be a long day before I would download any SP from
Microsoft the moment it is released....let others do the troubleshooting for
Redmond first.
I have never had any issues with any patches or Service Packs.
As usual after proper preparation, I will likely install SP 2 within a
few days of release.
I expect no problems but if there are issues, they will be dealt with
quickly.
