1) Do you think about this news will happen ?
I don't think so because bitcoin itself is an alternate payment method and somehow better than paypal.
2) Do you think paypal may accept bitcoin in next years (3-7) or it is impossible ?
Although nothing is impossible but the probability of happening this is very very low.
3) Do you think bitcoin will be better than paypal ? when will happen ?
Not will be but bitcoin is better than paypal in many ways.
4) which better for now PP or BTC ?
I never believe that Paypal is better than bitcoin but for now BTC is not accepted in most of the online stores so paypal is not a bad choice for now.
