No, they are starting to show up. Intel did say that things would be building into the holiday season. So expect plenty of 10th gen (both the 14nm kind and 10nm kind) by Black Friday.
Here's a dell you can buy now with the 10th gen, 10nm, i7-1065G7:

It won't arrive until Oct 9th, but that's not too far away at this point.
Not sure what you mean about "Pro" as in the iPhone Pro. The MacBook Pro has had a very clear distinction from the MacBook or MacBook Air for a long time. Are you wondering why it would be a "Pro" 16 vs the "Pro" 15? If so, think of this a bit like how they rolled out the original retina. If they release now, the 16 will be stuck on 9th gen. I don't think we'll see a 13/14 with 10th gen until next year, when the 16 could also move to 10th gen. Oddly of course, the 16 will be on 14nm 10th gen, while the 13/14 will be on 10nm 10th gen.
Also, and not directly related to your comments, I wouldn't be too terribly upset about the 45W parts not getting 10nm 10th gen just yet. CPU performance differences are pretty small due to low clock rates on the 10nm parts counter balancing the IPC gains. That impacts battery life, but for many that's taking things from good enough to even better. The other big distinction is the integrated graphics, but the 16 is likely to always come with dGPU cards, so meh. Also, Intel has worked hard to port over LPDDR4X to 14nm 10th gen, at least in Comet Lake U series, as well as other platform features. That's a big deal. It suggests that 10th gen 45W parts will probably get this as well.
