Not really, unless you have problems with certain media.
All available firmwares are currently RPC-2 ( = region locked) and can be found
here - if you need changing regions you must either use a region/encryption hacker (like anyDVD), or Linux (as the decss module there works completely independently of the drive's region).
Most likely, there will be either RPC-1 or self-resetting firmwares for it in the near future.
