We'll probably hear more about it at Google I/O in May. We can only guess when this device will come out. There's a good chance Google will fix that problem with the new generation, since using an older codec just produces more bandwidth costs, and that means more money out of Google's pocket.

Google is having YouTube lean so heavily into AV1 that it is building custom AV1 transcoders for its server farms. AV1's superior compression and royalty-free licensing have earned it the support of Apple, Amazon, Netflix, Microsoft, Samsung, Intel, Facebook, Arm, Hulu, and a ton of other companies.

AV1 is Google's latest video codec, building on the success of VP8 and VP9.
