MOM 2005 and SQL 2005
Ok, there is no official word from Microsoft on this yet but I have tested upgrading a SQL instance hosting the OnePoint and SCDW databases from SQL 2000 to 2005.
As long as MOM is running SP1 and you leave SQL Reporting Services as 2000 (do not upgrade it), everything seems to work OK.
There is no 'official' word from Microsoft at this stage the word is that there might be a KB article about MOM support for SQL 2005 in the near future.
Guess we will have to wait and see. If I find anything else out, I'll post it here.
