Yes , by the only way that we can see this news , is only the estimation side .
The product is hot ( Fresh) and still its not properly presented .
My estimations is that the price would be half than the FL-40 , lets not forget that it is a full TTL flash , but with not the programmable extras ,or the power of the FL-40 .
I do not also forget , that there is nothing with the Olympus logo on it, that comes cheap !!
From the size of it , i think that it needs only 2 NiMh batteries ,and the 8- 10 meters distance looks good for this size of flash .
As about compatibility , i do not have any doubt ,that this flash it will work with the most digital models .

I would expect to see also one more light design of the Olympus flash bracket , but hey , this is the last thing that it will bother me .
The FL-20 looks fine for the most common shooting needs .
I have notice that the plastic cover of it ,is one diffuser , that it can easily removed .
The effective distance of 7 meters is good , this flash in one extension of the cameras internal flash .
The on board flash can operate for macro to telephoto .
The external flash can operate from Wide to Telephoto .
The law of logic tells as ,that you always need to get the right tool for the right job .
