I am also intrigued by the next design, however I am pretty sure the next keyboard will be very similar or identical to the one now. A smaller keyboard was one of the last things that Apple needed to change to fully commit to their “thin and sexy” design aesthetic on the MacBooks.
I think they are very proud of their clicky, low travel direction and don’t see them going anywhere else.
Personally, everything about the 13 inch MacBook pros was working great for us, besides the keyboards, which makes it even more aggravating. 14 out of 18 machines!
If it wasn't for the keyboard, i would of purchased a 13" by now. I simply can't take the risk at the moment, the 2019 keyboard doesn't have enough evidence that it's been fixed or not. Yes i could get it fixed if it breaks, however as someone who writes EVERYDAY, i simply rely on my Mac to do that. Also sending it into Apple will take at least 24 hours for a fix. Yes i have a 2012 iMac (which i'm using to write with at the moment) but the inconvenience simply isn't worth the risk.
There are 2 things i'm personally looking for from Apple, a new Macbook Pro with a fixed keyboard and a redesigned iMac (the reason i haven't upgraded my iMac for the home office). I'm hoping that Apple delivers at least one of these things either in October of this year or next year.
The thing is i don't like Windows, i brought a Surface Pro 6 in November of last year, i learned that lesson fast. It's ok but Windows still isn't anywhere near as good as MacOS. So in a sense Apple have got me cornered, it's nothing new tho, it's been that way since i brought my first Mac back in 2011, it really was the perfect machine (for me).
14 our of 18? that is REALLY bad

the thing is i fear Apple are damaging the Mac brand, if i've held off buying how many others have been thinking the same
And before other people start saying i'm hating on Apple, i'm really not. I'm a big Apple fan, i own nearly every Apple product there is (Watch, iPhone, iPad Pro, Mac, Apple TV 4K, HomePod), BUT i do think they have made a mistake with the current keyboards. They need to fix them or redesign it. (hopefully they have fixed the keyboard with the 2019 update).
