That's up to you to decide, I paid $550 NZD at launch for the PS4 but wouldn't pay that price for a switch at launch. All comes down to preference really and how much value you personally thinks its worth. Since I play 80% of my games on Sony consoles I hold them as higher value so I'll risk paying more. You might be different and play 50% on xbox and 50% on Nintendo for example so could be on the fence about getting it straight away.
Anyways Im rambling about nothing lol just buy it if you want it or wait if you are unsure xD
