Android Photo Gallery VS G+ Photos App?

I have a feeling that Google is eventually going to phase out the photo gallery app altogether and make the G+ photos the default app photo app as a means of growing it's G+ user base.

I have been avoiding G+ for a while but Google continues to make the walls of the G+ garden narrower and narrower. Eventually, users will be left with no choice but to be a part of G+ by default when using an android device.
