Does anyone think the delay upon delay will hurt JJP's reputation in the market place ???   

Initially - maybe, but subject to the publics reaction to a finished game it may only be a small percentage because initial frustration could quickly change if the game is successful. Providing JJP produce a string of high quality games (fun and appealing), continue to innovate and achieve their own set deadlines for future releases, long term I don't think so IMO.
I'm sure they will learn from a lot of things - what worked, what didn't etc, set up systems and procedures focusing on the long term.

It may initially hurt sales, but I'd say people that may be interested in buying a WOZ are holding of now until a finished product is released before committing.
