Interesting. Some calls (Europe and some Caribbean countries) are cheaper with the new card, but some are much more(some Caribbean countries are very expensive such as Cayman Islands and St. Vincent). The call calculator on their website will do a cross card comparison.
Also note that the new card adds several new countries but is also missing some. New Zealand, British Virgin Islands, American Samoa, Ivory Coast etc. are new countries.
Also there is a seperate FAQ for the new card and it doesn't rule out UMTS data as a future offering like the old card:
"Q: Can I set up UMTS with United Mobile data connection?
A: No, this service is not currently available. If you would like to subscribe to our Newsletter, we will keep you informed of latest developments, like for example UMTS."
This qualifying language might have something to do with the investment by the Skype founder. Wouldn't hold my breath on data anytime soon but they aren't ruling it out.
