Should I wait to buy a gaming laptop?

I have finally decided to make the switch from PC to Laptop as I need the extra convenience. I was planning on buying a laptop with a 4070 (as I would still be using it as my main gaming device) which from what I’ve seen are priced around £1200-£1700. But I understand that with the release of the 50 series laptops only being a few weeks away, the prices of the 4070 laptops will obviously change. But I was wondering if the price decrease would be a plausible amount to wait a few weeks before buying? Also, I should make it clear that although the 5070 laptop will likely fall into the price bracket I mentioned earlier, I would like to ideally spend less than that. Would also appreciate some good laptop recommendations if anyone has any as I know next to nothing about gaming laptops!
