Finally a successor to the awesome Sony Ericsson K800i seems to be imminent. The K810i is expected to be launched in Q2 of 2007. It seems to be very similar to the K800i (3.2 mp camera, Xenon flash, etc.) albeit in a slimmer form-factor and with a unique button design. It remains to be seen how well these buttons will be taken by consumers but I must add that it looks sleek (something which the K800i lacked).
Also there are some photo enhancing tricks along with easier access to the camera settings. It would be cool if it has WIFI support, but I didn’t see mention of it anywhere.
