This compiler performs far more aggressive optimizations than the client compiler but has a slower warm-up time.

You will notice that JDK6u18 early access release has a HotSpot that is almost the same as the one from the latest JDK7 snapshot (HS16b08). Similarly, JDK6u16 has a HotSpot that is almost the same as the one in a JDK7 snapshot from some months back. Basically, Sun has been including a new HotSpot in JDK6 every few releases (JDK6u4, JDK6u10, JDK6u14 and now JDK6u18, although the latter is not yet final), so one can get access to HotSpot improvements without waiting for JDK7.

From Sun? Only from Sun? And where is IBM? Where is Oracle, Redhat, Intel, HP, Nokia and the rest?

I think that single biggest change in JDK 7 will be invokedynamic together with all the infrastructure for supporting more dynamic languages – it will have major impact on their execution speed.
