I am working on a (time-sensitive) project using an RPi3 Model B, but I require as much computational power (for computer vision application). I heard that the new RPi3 Model B+ is out and has a better processor, better Bluetooth (important for my application), and better thermal management.
I have heard about how the Raspberry Pi products typically run out very quickly and that there is a long wait before the next stock comes out.
Also, I am using a touchscreen (PiTFT), which Adafruit says is not currently compatible with the new RPi but they will update that soon.
Also, I wasn't sure whether or not the NooBs OS for the Raspberry Pi 3 Model B is compatible with the Model B+.
Therefore, my question is, given that I need to build this project by early April, do you think there would be any advantages to wait until then to buy it or should I immediately buy it now? I guess I am concerned that, given this is a new product, whether they might be any sort of problems that prevent its application in my project (for example with regards to the PiTFT), and that I might be buying this device assuming that these problems would be fixed in time, but eventually is not done so in time for my project.
P.S. - Let me know if this question is too broad and how I can improve it, given that this is my first time on this website.
