And if you already have 4.1, do you still get all the updates for it, or do you have to buy 4.1FE? Or is 4.1FE mainly like service pack which gathers all the updates till now and is sold mainly to new users, but old users can continue updating their existing 4.1?
No, SSolie confirmed at Amiwest that there won't be future updates unless you have FE.
