Last week we had 7229 leak and this week it's build 7232.winmain.090610-1900 that has wriggled out of Microsoft's Redmond HQ and is being distributed across the net.

The most obvious visual change is that a new default wallpaper has been set and there is no more betta fish. Windows 7 is still on track for a July RTM, and it's possible that it may even RTM by the end of June. Microsoft has announced that it will be available in stores October 22nd.
