Integration Space, Who remains?

After webMethods's aquisition, 0nly pure play ESB/Integration ISV that remains in the market are TIBCO (going strong and moving into other areas such as AJAX), IONA (which has developed a decent open source strategy as well as has a legacy of CORBA Servers to sustain on 2005 –ve, 2006 +ve) and Vitria (already burning money ;-ve net income in last two years). See the graph comparing their fortunes from Google Finance.

There are other integration tools such as Sterling Commerce (very strong in EDI and SupplyChain Space) from AT&T stable, and Seebeyond (now part of Sun), We have to wait and see how they grow.
