I don’t think a HomePod 2 is coming anytime soon, maybe in a couple more years... maybe...
From apples perspective, they have a HomePod which started at over £300 (way too expensive), didn’t sell well and so reduced it to £280, and let’s be honest it still isn’t doing well.
I can imagine another price drop in the near future, I think the only time the HomePod has had half decent sales is when it hit £199 here in the UK and even then it wasn’t a huge hit due to its age.
If Apple even considered a refresh it would have to be retailing at £200-£250 maximum out the gate it’s just whether Apple feel the profit margin is worth it and also if it’s worth taking the risk.
Apple are well aware the current HomePod is more welcomed into the market at £200 hence why they are giving an £80 voucher in the Black Friday deal at the moment.
The only thing I have got to say for Apple that even though HomePod is technically a failure, they are still bringing new features to it 3 years later.
