smsharma,
MyEclipse Blue 8.0 supports WebSphere 7. At the present time we are focusing all of our work for WebSphere support into our MyEclipse blue product and do not plan any WebSpere-specific enhancements in our Pro line. This strategy has been in place since the Blue product launch 3 years ago in order to allow us to create a best of bread IDE specifically for WebSphere users. The very basic WebSphere support in MyEclipse Pro exists simply because it predates the availability of Blue.
However, if you’re a WebSphere user, Blue is really the right product for you; just look at these Blue only WebSphere features: http://www.myeclipseide.com/module-htmlpages-display-pid-1.html
In 8.5M2 we have added a WebSphere Application Editor and support for Portal Server 6.1: http://www.myeclipseide.com/module-htmlpages-display-pid-449.html
If you’d like to upgrade your subscription, the price will be the simple cost difference based on the amount of time you have left on it. The folks at subscriptions at myeclipseid dot com can help with that if you drop them an email.
