50-200 swd or not for mFT

A bit of a hypothetical question ,I believe from reading posts in the mFT forum that though far from speedy the non-SWD version of the 50-200 is a little quicker to focus on the current mFT adapter. Now, for the hypothetical part of the question. When Olympus brings out the next high end mFT camera, with the adapter to allow proper use of the FT lenses. Is it fair to assume that the SWD lens will then have the fastest AF? I appreciate that the answer is going to be a little speculative. Although I don’t know the specs of the future high end model based on the OMD I will be hopefully buying it, the relatively small size of the OMD with to me fiddly controls and its poorer video implication are the only reasons I bought the GH3’s. Hopefully the next body will be a bit larger and a bit better ergonomically.

I am not an avid telephoto shooter however I would like a bit longer than the 35-100 { which ,is performing very well} and the 50-200/SWD delivers a lot of bang for the buck. Apart from the hopeful gain in AF speed does the SWD have any other notable improvements

Thanks
