There's some news
here on the US replacements.
Essentially the DMR-E80HS in June sounds like an HS2 with 80 GB hard drive and no card reader or DV input. While the DMR-E100HS in July sounds like an HS2 plus 80 GB drive and an additional SD card reader.
Both
should have the option to choose 0 or 7.5 IRE black level on the input just like the DMR-E50. However, the black level bug is a North American only issue (due to the 7.5 IRE setup), it's not a problem in Europe because setup used there is 0 IRE.
