upgrade mean :
Losing a significant amount of time trying to resell a base Steam Deck with a 1TB disk for approximately 350e. If you opt for the 64GB version and add a 1TB NVMe, your total loss is 150e (100e for the SSD and 50e for the deck, given the original cost was 400e).
There’s a reliance on luck for the newer model to be in stock after selling yours. In Europe, it’s priced at 570e. Considering the loss from selling the base model (570e-350 = 220e in loss + the 150e you loose selling it comparing to its base value) so it’s a 370e upgrade
it’s the price of another base 64GB Steam Deck and this is assuming the buyer isn’t trying to scam you.
They also mention that an oled screen would be very complex.
and a z2 chip or rldna 4 chip could be released next year
