I only had five games installed beforehand that I can vouch for in terms of installation size, so here they are, pre and post-XBL preview update:

Halo 3: 6.3 GB -> 5.7 GB (-9.52%)
Lost Planet: 6.9 GB -> 6.8 GB (-1.45%)
Lost Planet Colonies: 6.7 GB -> 6.6 GB (-1.49%)
Resident Evil 5: 6.8 GB -> 6.7 GB (-1.47%)
Street Fighter IV: 5.7 GB -> 4.6 GB (-19.3%)
