Prim sizes

Did I miss something? From many of the threads I'm reading I'm getting the feeling that it is possible to have a single prim larger than 10 meters now. Is this the case? Does this mean I can have a single prim be the floor in my house? As it sits atm, I had to tile 6 prims together to make the floor, if this IS the case, then maybe it won't be *quite* so bad.

Anybody? A link would really rock.

i haven't seen that. it would be nice to have 20m prims though. i've also been told that once you link several prims into single object, the whole thing only counts as one prim. wouldn't that be nice too!
