I find that very unlikely actually. What SoC would it run? AMD hasn't released anything stronger than the Z1 Extreme (which is just a power constrained laptop part) so the only alternative would be a variation on that, maybe one that works better under a tight power budget just like the AMD chip in the Steam Deck? However I'd argue, as a ROG Ally owner, that battery life improvements aren't really that high on my wish list. If I could get anything it would be optimizations making the experience more stable and improve 1% lows. But most of that I don't think is even on Asus, it's more on AMD to tweak their drivers and on the game makers to tweak for the Z1 Extreme, which thankfully is in more than just the ROG Ally so it does make sense to do so.
