Yes performance does improve a great deal as the browsers pre-fetch in
parallel. Its definitely a long overdue feature for browsers :)
But it will still should be more efficient / faster to do one request
instead of many in parallel. Even with parallel fetching the default in
the Firefox nightlies its 5 scripts at a time. So you still end up doing
a few round trips when you have a high script count.

Note that this should be dramatically improved in next-gen browsers
like Firefox 3.1, IE8, and whatever the next stable branch of WebKit
is. All of these three can now load scripts in parallel, last I
heard.
