This Press release is a bit more comprehensive, although it may only refer to the German Market.
It states the roof rails are only standard on the Style, rather than the R Line as mentioned in the Video which is good.
Also states that the Matrix LED lights are Standard on both the Style AND the R Line, whilst the VW web page states only available as standard on the Style, which would be a shame.
I think 18" silver Alloys should be standard on the R Line (as on my current R Line T Cross), The Taigo R Line only has them as a Black option,
