Yawn.......this is not BG 1& BG2 - its not trying to be - leave those games in the past they are classics & everybody knows that (boy do we hear about it enough..)
Yes it has BG3 as a title its based (largely) in balders gate & follows a story 100 years later ....this is not trying to be a sequel to the other 2 games - its drawing on the influence of those games & yes it is a bit of marketing there but this is a new vision - the 3 games can exist in the same world setting.
