Hopefully they can put out a Blu-ray machine as good as the BD390 but for a cheaper price and perhaps a smaller form factor.
Edit: It appears the new models are a bit smaller and don't seem to offer many features over the older BD390. The BD590 does add a 250GB HDD to store video which can be nice for people with too slow an internet connection. I wonder if the BD550 will support .mkv from an NTFS format drive. It does seem odd, the omission of HDMI 1.4 and 3D. Oh well, not super important to me anyway.
