I think JSP 2.0 will come with the Jakarta Tomcat release (4.2.x whenever that
is, when Jakarta will implement the reference implementation). So we will
get the features automatically like the Expression Language. In the Struts Dev
list there is some talk about Struts HTML tags and how they fit in the new
EL in JSP2.0.

You mentioned writing Servlets. Nobody writes individual Servlets any more 
except for special applications like web services or research. Struts allows us
to concentrate individual web actions or in Expresso controllers.

The most difficult part is now the View (normally JSPs), but even that has
made simpler because of Struts Templates, and then advances with
Cedric's Struts Tiles.

JSP 2.0 will definitely help toolmakers ie DreamWeaver MX 2nd Edition 2003
when there are definite DTD elements for icons, examples in the tag library 
descriptor files. Yes JSP 2.0 will help script designer write simple tags
too. It is about 6-12 months distant.
