Sun Microsystems has released a beta version of the upcoming StarOffice 6.0. There is not an OS/2 version but I was able to install it using Odin under warp 4.5 MCP. There seems to be much improvement over 5.2 specifically for me is the elimination of the integrated desktop and also it has support for XML file formats. FYI the beta expires March 2002.
