here is my thoughts:

1.Performance front:

We can expect 256 GB RAM and 100 TB better version of SSD, 4 times faster processors and may be consistant 100 MBPS wireless Broad band speed

Impact: there wont be performance problem in small/medium scale databases as most would be in memory databases. We can expect cheeper in memory solutions in another 10 years.

2. some DBA tasks:

We can expect better in build options like

1. options for auto archival

2. options for intelligent auto indexing and intelligent defragmentations options

3. better options to handle too much file growth (like tempdb/log file growth)

Impact: day to day DBA tasks would be inbuild options in another 5 or 10 year.

3. High availability:

We can expect same Clustering/Mirroring/Backups features with some improvements.

Impact: Even a junior DBA/developer will know on how to recover data with 0 data loss.

4. We can expect inbulid team based development suite (like vss)

5. DBAs will be forced to learn .Net, Cloud and SSIS & SSAS for survival.
