Mirrorless rumors: Samsung NX100 presentation on September 14, Panasonic 21 and something from Pentax and Canon?

After the somewhat disappointing Olympus announcement what can we expect from other brands?

1) Samsung will announce the NX100 on September 14. It will be the first compact NX camera and it uses the same NX10 sensor.

2) Panasonic will announce the GH2 on September 21. This is really one of the most interesting product announcements!

3) There were “weak” rumors about a mirrorless camera announcement right before Photokina. Accoridng to Canonrumors “someone had see 2 pancake lenses from Canon for the new camera. A 24mm & 55mm.“

4) A big surprise could come from Pentax. They already announced that they will make a mirrorless camera which will be very different from current models from other brands. The question is, when are they going to announce the camera? On September 9th?
