Hey! So. I currently own a PS5 and I just got a steam deck as well!! There are definitely reasons to get or to wait for a PS5! It all comes down to what games you’re looking to play. I’ll say since I got my SD about a month ago I haven’t touched my PS5… catching up on some games I missed in the last 7 years has really taken up a ton of FUN times. Things like CDKEYs and humble bundle mean I’ve been able to grab games like Bio Shock Infinite that I somehow missed, for only 4$. And playing that in bed or on the couch or on a break at work is awesome! It’s like having the power of a PS4 in your backpack.
But if there are AAA Sony games you’re just dying to play like GOW or Horizon it’s tough to beat those games on a nice 4K tv with full surround sound.
I realize I might not be helping you make a decision. But this has just been my experience!
