I pre-ordered the Metal Gear Solid 4 Limited Edition Playstation 3 Bundle yesterday from Konami.com. I was debating between it and the standard MGS4 bundle for a long time, and I was swayed by the collectible status of the Limited over the 40GB advantage of the Standard. Well, that's just the thing. I thought the only difference between the two is the HDD capacity. I now realize that besides the capacity, the 40GB is also missing PS2 compatibility, SACD support, and it does not have a Flash card reader. For PS3 owners of 60GB and 80GB (that has these), save for the PS2 compatibility, are those other features a deal-breaker? Thanks.
