I live in Thailand. I went to the Samsung store yesterday and preordered a Note 20 Ultra. They had two colors, bronze and black. Memory 12GB/256GB and 12GB/512GB, both 5G. I'm getting the bronze, 12GB/256GB because I will use the SD Card for pictures, music, and backups etc. Currently on my Note 10+ I use only 67GB of the 512GB so I saw no need for the 512GB on my Note 20 Ultra. The price was 42,900 baht, about $1,380, the 512gb version was 46,900 baht, about $1,500. I get it on 8/19, 2 days earlier than most other countries.
I played with the demo Note 20 Ultra that they had in the store. It doesn't feel much different than my Note 10+ or look much bigger. And the bronze color looks like bronze, not pink like some of the photos we have seen.
