Adobe After Effects costs 19,99/annual at least, that what says this page: http://www.adobe.com/products/aftereffects.html
Does it mean, that if I keep paying 19,99 each year, I get also future versions of it? So it's technically 19,99 per year for any updates et cetera?
No, that is not $19.99 per YEAR, it is $19.99 per MONTH, when you commit to one year of rental
Annual plan for US $19.99 per month
