It might also be working less in Valve's favor since the Steam Deck is technically a PC, might also not have as lucrative deals like Sony, Nintendo, Microsoft in memory either.
With all that being said though, the Steam Deck is NOT worth it for about $1000 with tax. People glazing the ROG Ally are going to be very disappointed when that also gets a price hike.
Edit: looks like the 1TB model went back in stock
