At 8 weeks it is going to be very difficult to tell how big she is going to get just by looking at her paws and her current size.
But, she IS going to be a big girl!
Most likely she will be 120 - 130 pounds, since it appears that the Rotty and Mastiff are showing to be the dominate breed traits showing through.
She'll have a pretty big growth spurt in about 4 to 6 weeks from now - her weight will probably almost double in that time (as long as you are feeding her a good quality food).
Around 6 months of age you'll have a better guess at her adult average weight - she'll be about halfway there.
Since she's definitely a large breed puppy, be sure that she is on a large breed puppy food, and a good one (the large breed formulas have more protein). Also, if you plan on doing any type of sports with her (agility training, for example), keep in mind that her joints will not be ready for jumping until she's about 18 months.
Look into some basic obedience training NOW, since she will be very hard to handle (most places allow you to start training them once their basic puppy shots are completed, usually around 10-12 weeks)
