Assuming we are in a case similar to M1061 (which is the most probable case, considering that there are many more large prime candidates than small prime candidates), you will need some more computers and some more lifetimes to get a factor of M1277 by ECM or P1. The TF is totally out of discussion, you need few lifetimes to catch the point where ECM is now...
This not considering a lot of "experiments" that other people run on this number, which are usually not reported to gimps. If the factor would have been some "low hanging fruit", it would have been found up to now. My bet is that the smaller factor has over 100120 digits, most probably over 155 digits (the half of 385 is 192).
I would be very happy if somebody proves me wrong by finding a factor, hehe...
