Toshiyuki Terada, Product Manager of SLR Olympus Planning Department, on Fotopolis when asked about smaller-than E-5 SLR cameras:
We do not have concrete plans to replace the E-620 and other recent SLRs. The entry level SLR class can be completely replaced by the Pen system in terms of performance.
The ultimate goal of Olympus is to go PEN 100%, no more DSLR. via Photo Rumors
