I bet they're working on improving the AA battery powering. It has been big brother's (FR-2) bane. When the FR2LE first debuted at Musikmesse in March of this year, the exhibitors released info that the FR2LE could run 8 hours with a Tamiya RC3600HV, Ni-MH battery (RC battery pack). No mention of run-times for internal AA batteries. Since then, some info has been released that the LE can run on AAs. Nothing else. No press releases either. Internal powering has to be their main issue right now. I can't see releasing the LE with the same powering issues as the FR2. It would be a marketing disaster if they didn't address that. Mentioning a RC battery pack is a red flag. That's odd when compared to their competitors' internal powering solutions (AA's).
If they're adding digi-in, I wonder if it requires a complete redesign. Anybody know?
