Today Oracle announced the acquisition of Sun, only 2 weeks after IBM cancelled the acquisition talks with Sun. I'm not sure what this will mean, as Oracle has been moving away from Sun for a long time. This might impact the close relationship Oracle has cultivated with both HP and Dell. It looks like Oracle wants to broaden its horizon into hardware as well, which was already indicated last year with the introduction of the HP Oracle Database Machine.
MySQL, only just acquired last year by Sun, becomes the latest addition to Oracle's database portfolio. Will this mean MySQL will no longer be OSS? Personally I don't think so.
