Absolute 3, best way to buy?

What’s the best way to buy Absolute 3 collection? Website says if you purchase A3 now you’re entitled to a free update to A4 when released in Janauary. I’m unclear if that includes GA5 (full) as a free update, or will there be an additional charge for that?

Thanks.

it should be included free because I have absolute and theres no way for me to upgrade groove agent and even in the absolute page it says we have to wait until absolute 4
