4805 is actually up on the infocus website now.
Zipbags, if you are interested in this PJ & have a low ceiling (as I do too) I would highly recommend that you wait until we have some info about the offset of this PJ, offset, incase you are not familiar, is the distance the image will project above or below the lens depending on weather you are ceiling or desk mounted (below for ceiling, above for desk) The 4800 has approx. 132% offset in 16:9 mode, the 5700 is 133%. Based on the 4800 numbers this would mean a 45x80 screen would need to be placed approx 15" below the lens to avoid the use of tilting & keystone. Add to this the depth of the PJ base to lens (3") plus another couple of inches min for the ceiling mount, so best case is that the image is 20" below the ceiling. As you can see this is not so good for low ceiling rooms (unless you like your picture next to the floor). My ceiling is 6'-6" where the PJ needs to be mounted due to a duct running the length of the room, so I waited for hard info on the offset for months & in the end ordered a differnt PJ which has a smaller offset & lens shift, as I have a feeling that the 4805 will have a similar offset to its brothers (4800 & 5700) and will not work for me. Anyway, I just don't want anyone to get a PJ to find it won't work the way they want it to, I did this with the BENQ 6100.
On the other hand if the offset is closer to that of the 7200, it may still work out for people with low ceilings, 7200 has 116% offset hence 7" approx below lens, for an overall offset of around 12"
I am hoping the offset is small, as I would still like the 4805 if the reviews are as I imagine they will be. On the other hand people with higher ceilings are probably hoping for a larger offset so they don't need to hang the PJ low. I just wish all PJ's came with lens shift, at least vertical, it makes life so much easier.
If anyone knows the offset I would love to know too.
