Vicki it'll be there quick. Silly ups guys what's up with them stopping to break their tooff anyway?! You'll want to get a big garbage bag when the frame arrives because Dave packs the heck out of the box for protection.
Bike fit isn't totally stagnant. We tend to get more limber as the season progresses which will often lead to the bars getting lower, longer, or both. The saddle "may" go up a little but what I've found over the years is that people will often ride better later in the season if the saddle goes back a bit and is level as opposed to nose down. Generally but not always a nose down attitude is to compensate for a saddle that's a little to high. Rocking hips and toes pointing down are usually the most visual indicators of that also.
My position has changed from my racing days in that the saddle to bar drop isn't what it use to be, the saddle is slightly lower but it's also a little further back which helps with my bad back as it allows for a pretty comfortable and efficient position. Of all the things I've seen over years funky saddle position has to be #1 by far.
