I know the sat is not in the standard acquisition phase, the data are not yet in final quality, but I suppose it is already on stable orbit and doing much more acquisitions than we can see samples of in the news. Maybe it will be like it was with Landsat 8 - when the calibrating and testing phase ended for Landsat 8, a bunch of scenes from the testing phase were released for the public, and these data, processed with the final algorithms had also the final quality (only the first images had better spatial resolution due to lower initial orbit). But for our research, these data were virtually useless, because we depend on data measured in-situ at the time of satellite overpass, and since we did not know when these overpasses happened, we did no do the measurements. I would rather not repeat such waste, and would do the measurements even if availability of the images is not guaranteed. Especially because now is the best season for cloud-free acquisitions over the central Europe...
Here is a link to the ONLINE SATELLITE TRACKING service (http://www.satflare.com/home.asp). You can find the required satellite and track online its movement using “Satellite Search” in upper left menu. To see the passage of the satellite over a defined location you must specify the coordinates using “SET YOUR LOCATION” and click “PREDICT PASSES” in the bottom menu. 5 Day Predictions table for all of the satellite passes for your location will appear at the end of the page.

Thanks Dmytro, I have seen such services, but did not realize this particular use... It works well. For others: I met one difficulty, was not able to find the satellite by putting Sentinel-2, Sentinel-2A, Sentinel in the search box... until I realized the name must be all caps, so use SENTINEL, like this.
On second look, I have found the overpasses found there did not correspond to scheduled acquisition times for Landsat I know, so probaly not good for Sentinel-2A as well. Maybe I just did something wrong way.
I had better luck on site http://www.n2yo.com/?s=40697|39084|25682 (this is direct link to map tracking Landsat 7, Landsat 8 and Sentinel 2A. The way to get acquisition overpasses on that site:
1) If not detected correctly or not the location you are on now, select the location (box right bottom of the map).
2) Click the sat on the map.
3) Click the blue box right of the map [10-day predisction..].
4) Click the [All passes] button on top of the table.
5) Find the pass(es) with elevation above 80° with worst observation conditions (white cells - means daytime).
Seems to work well.
Below you will find the location information of the Sentinel-2 satellite (TLE):

You can use STK from AGI.com. They have a free product where you could load all satellites with the actuel TLE (Position) data and view it in 3(4)D.
Thanks Uwe Bacher, this looks really interesting, and now I also know what is the use of the data posted by Fethi Benhamouda.

You can also have a look into http://www.agsattrack.com/?view=3d
it is an online app build with agi tools.
Hope this helps,

One more option:
ESA supplies the Sentinel-2 Acquisition plans in a kml format. The data shows the planned overpasses for a few weeks ahead.
https://sentinel.esa.int/web/sentinel/missions/sentinel-2/acquisition-plans
Thanks, but this question is now irrelevant. It dates back from the time, when Sentinel-2A was in deployment phase and there were no acquisition plans and no imagery was disclosed yet, but some had been already produced and released later.
I used the acquisition plans in kml format like Elias Berra sugested. It predicts the passing date and time of the satellites for a couple of weeks in advance. Works well.

For anyone stumbling on this old question, maybe have a look at https://spectator.earth. It shows the current location of many Earth observation satellites and provides a list of past and future acquisitions for a given AOI.
(Disclaimer: I know one of the developers of Spectator)

Hope this helps,
Elias Berra Hi,
The acquisition time is based on local time or not?
