Here's the thing though, most of this list isn't really accurate. The Sony is about as bright as the 5030, and the 5030 is brighter than the Panasonic. It's not about advertising, it's what you end up with after installation and calibration, and in that regard, the Sony is a real winner.
The DI is certainly on the Panasonic, so any advertised (once again - advertised) contrast ratio advantage, basically goes away when used in the real world. Plus, if you find that you don't like the DI, then the Sony has a huge advantage, because it achieves it's great contrast ratio without needing some artificial enhancement.
As said, automatic zoom only matters if you intend to use a 2.35 screen, which most people shouldn't be doing because their room isn't right for it. It's a great, extremely limited use, feature.
Lamp life remains a crap shoot. Period. Anyone who has 1,000 hours on their lamp should have money in the bank to buy a new lamp. Until manufacturers warranty lamps for the 2,000, or 5,000 hours they rate the lamp to, you really are on your own with this, and it's established that lamps can fail at almost any point. Still, it could be a plus for Panasonic. Just not much of one.
Rebate (or more accurately price) is obviously always worth consideration. But, any projector within a couple hundred bucks or so of another projector is certainly in the same price range I would say. But, it does save you a couple hundred at this time. Maybe not so much the case when you are ready to buy.
I really like both Epson and Panasonic, but if I were to buy right now, there is no way in the world I would buy either of those two brands over the Sony.
