As one of my teachers, one may assert anything.
1. What is your source for your claim that the sensor is two years old? It may well be, but I for one think you either made the number up, or stole it (i.e., used it without attribution) from someone else who made it up.
2. Sensor performance is not improving all that fast. In fact, a majority of the current improvements are occurring in the downstream imaging pipelines.
Again, I would suggest that you're basing your opinion on uninformed speculation, not on facts about the camera's performance or capabilities.
It may be a dog, or it may be a gem. It may be a great value or a terrible one. At the moment, we have mainly hope and limited information.
