LG is going to introduce G6 in Barcelona, Spain on the 26 February and start selling on the 10 March. Presale for G6 will take place from the 2-9 March. Samsung is going to introduce the Galaxy S8 in New York on the 29 March and launch it on 21 April. Presale for Galaxy S8 has not been figured out yet.

LG gets 42 days march on Samsung and this is the first time when LG has beaten Samsung to the punch. It will be about 50 days earlier if  the presale schedule is included. However, they are more or less releasing at the same time, which means that a war is expected in a way not seen before.

Initially Samsung was going to launch the Galaxy S8 globally on the 21 April and domestically a week earlier. Its original plan was to have presale on the week of the 6th April and launch the Galaxy S8 in South Korea on the 14 April. To have stable supplies, it has modified its plan by having Galaxy S8 launch globally and domestically on the same day.

So it looks like both companies are competing against each other before they officially launch their premium smartphones.
