Is chess.com planning to get its own tablebase?  I know there are lots of free tablebases on other websites, but I've seen a couple forum questions recently that could have easily been answered with a tablebase, and I think it's more likely that the posters would have know about tablebases should there have been one on chess.com.  In addition, it could help catch cheaters--if they're stupid enough to enter a position from one of their games that are still in progress, you swat 'em like a fly!
