Yes, detecting neutrino is a new technology and we might very well detect more supernovae in our own galaxy than ever before.
The rate of recent extra-galactic Supernovae discovery (in other galaxies) is at least 4 times higher than it was the case in our own galaxy.
And this is pretty odd.
Not if we aknowledge something was hiding them form our ancestors' view. Certainly all those dusty clouds, the huge number of stars.

In 100 Million years, our "descendants" or whoever will be living on Earth, won't know much about the Andromeda galaxy....
Because our solar system will be in the other side of our galaxy and M31 will be hidden by our own galaxy's bulge.
