Slated for March 27th release date, it seems that we've pretty much learned everything about the device already. According to Twitter user Roland Quandt (via MobileScout), the European price for the P20 will be €679 (around $835) and the larger P20 Pro will go for €899 (roughly $1,106).
What you get for ur money when buying the P20/P20 Pro (WEU):
P20 = 5.8in, 4/128GB = 679 Euro.
P20 Pro = 6.1in (not 6.01), 6/128GB = 899 Euro.
no other memory variants planned for Euroland, it seems. Other regions will get more variants. Some more official shots (size comparison): pic.twitter.com/ldi9oZ9jbj

Taking a look at the leak, there will be two variants planned for European release: the P20 will have 4GB of RAM and 128GB of storage, and the P20 Plus will come with 6GB of RAM and 128GB of storage. There will apparently also be other configuration options for other regions, and the price will reflect them accordingly. Keep in mind that European prices tend to be higher and include tax, so it likely won't covert 1:1 for prices in the US.
Huawei is expected to announced three P20 models next week, which are the P20 Lite, P20, and the P20 Pro. The P20 Pro is expected to feature a three-sensor rear camera system, which is first for a major smartphone.
