The View From The Bow: The future of the ESB market: "The ESB market includes Cape Clear, Fiorano, IONA, Polar Lake, SeeBeyond, Sonic, TIBCO, webMethods, and I'm sure a few others. In addition, superplatform players IBM, Microsoft, BEA, and Oracle are heading into this space. And Blue Titan, SOA Software, and Systinet all provide ESB-lite solutions. Definitely this market will experience some serious consolidation. More to the point, I expect that the ESB, WSM, and WSR markets will merge.
In the long run, maybe 4-5 players will survive. My bets are on Sonic, Systinet, TIBCO, and webMethods."
