Similar to the Pentax k-7 Silver, there will be a new Pentax K-5 Silver DSLR that will be announced next month (February 2011).
In addition, there will be a new point and shoot camera Pentax RZ-18 with 3" swivel LCD, 14MP sensor, 18X optical zoom (28-504mm) and a price tag of $300. The camera is expected to be very small in size.
The mirrorless camera from Pentax will be called NC-1. Pentax is expected to release two different EVIL cameras and I am not sure which one will be announced first. The RZ-18 and the NC-1 may be announced at a later date (not together with the Pentax k-5 Silver).
