Wait for mtw5 or buy mtw4

Hi, my MTW4 that I bought at release broke (yay!), but luckily I was able to return them to Amazon and got the full €300 back. So now I'm wondering if I should just buy them again since I really like the mtw4, or if it would be a better idea to wait for the mtw5 (since it has been 2 years since the mtw4 release) What are y'alls opinion?

As a side note: I know the new Sony's released but I read that they don't do well in the wind and that's an important thing for me.
