|All I know that an 80GB PS3 Metal Gear Solid bundle is in my future!
I think there are too many comparisons between the Wii and the PS3. I have a 60GB PS3 and a Wii and they serve different purposes. I usually play the wii more often when friends are over or when my girlfriend wants to play. Wiifit is an exception because it is setup more for individual activity. I had no problem finding wiifit. I ordered it via Amazon.
The PS3 is a media machine that is just now hitting its stride when it comes to gaming. However, many of the games are nothing like you get with the wii. I am not saying one is better than the other, they are just different. Personally, I use the PS3 more for Blu-ray movies than anything else, but that is starting to change with GTA, MGS, etc..
In other words, I won't be selling either of them.
I should mention that I got my Wii a few weeks after Christmas. I found it at Target. You may try this link
and see if there is anything out there.
