Here is a couple that I thought of:
Natural, chemical free fabrics.
Improvements in batting longevity.
Long arms, especially electronic ones, affordable for the home/non-commercial user.
Voice activated commands on sewing machines.
Sewing machines will sense how fast or slow you want to move the fabric through. No foot pedal.
Affordable electronic fabric cutting machines that do not require dies. If you can dream up a shape, you can cut it using a computer program. Even better, you can program how much yardage you have and set it to cut out multiple shapes all at once.
