lol i do the same

I heard the download version takes over 5gb after installation. The blu-ray version takes over 5gb of installation. What's the point of having the disk?

Disc

Because it looks sexy with my game collection. Also I can rent it off to people for cash, and let my family borrow it..

disck for me,

Don't forget the retailer take of $4-$5.  Also, this is unique in that Sony will publish the game either in store or online.  But most third parties will save a significant amount $10-15 by publishing online versus in store. 

 I can't believe that anyone would get the download.  A.  The price of the boxed version is cheaper.  Yes, you may have to look around, but it's easy to get Prologue delievered to your door brand new for less than $40.  The second is a month before the full version is out, you can sell it for $15-20.  So it's essentially like paying $20-25 for the priveledge of playing Prologue for a year before GT5 is released.

You can't compare renting a movie to buying a movie.  Compare it to renting an HD movie at a movie rental place.

@ FOOD:  The BD version requires a 5 GB install because it's basically the same thing as the PSN download, just on a disc.  It's not programmed or optimized to stream off the Bluray disc.  It's the same deal with Warhawk.  If you buy the BD version, you still have to install the full game to your HDD.  I'm sure this will change for the final version of GT5.

@ ConAir:  Prices for downloads won't be going down any time soon.  The majority of money games make are still made at retail stores.  If you undercut a retailer's price, they could and most likely would take your game off their shelves.

That's thinking in todays terms.  The future is online.  Yes, more and more games will go to digital only distribution.  It cuts significant costs.  There is no more guess work and having 500,000 copies of a game go unsold because you thought demand would be higher.  Publishing costs push prices way up as well.  It's been rumored that if a game sells for $60 the developer will only get $30.  By going online, they will cut these costs substantially.  You'll also sell to more individuals.  For example the only way for me to share my wiiware games is to actually take my wii with me.  So me and my friends that play will probably all have copies of the games we like versus having one copy and passing it around.  Do to these digital downloads should be cheaper.  It reminds me how credit card companies used to fight you transferring money from your bank account electriconically by charging you a fee.  But having an individual open my mail, go through the companies controls to the check actually got cashed costs 10 times as much.  So I would just send a check until they made online bank payment free.  Eventually games will be distributed mainly online.  Sure there will always be the Metal Gear Solids that would be insane to download and thus will be sold at retail.  But 80% of the games can work with download.
