Last year the Polish Glacier Direct was in great condition due to the heavy snowfall the previous winter. Many climbers didn't even use a rope on the Polish Direct and several climbed it using only trekking poles. They also reported few, if any, crevasses on the route.
My wife and I climbed the Polish Traverse (late Dec 2005 - early Jan 2006) and didn't use a rope or even crampons but there was on small section that was very polished with enough objective hazard that we took a mountain ax just in case on summit day. Here are two shots of the Polish Direct route I took last January showing the "bottleneck" and "2nd rock band". The only crevasses I know of were near the crest at the top of the route as the remainder of the glacier was very thin and in compression. As you can see in the first shot there are not any crevasses. The pictures are pretty big so click on them to enlarge them so you can get a good look. On the second shot you can actually see the route heading up the right side of the glacier, through the bottleneck and straight up throu the second rock band.

And here is a shot of high camp from part way across the Polish Traverse.
