What does the size of the hard drive have to do with PS2 backwards compatibility? This is really stupid if they won't support PS2 discs anymore -- it will certainly make me less inclined to get one.
The HD size really isn't relevant except to note which 'phase' of release the console was.
The 20GB & 60GB versions had (as I understand it) full hardware Backwards compatibility with PS2. These were the launch versions of the PS3
The 80GB version sold here in the States (but not in Japan?) has partial HW backwards compatibility and the rest done via emulation. This was the version launched in the US when they stopped selling the 60GB (they had already discontinued the 20GB version prior to this)
The 40GB version has no Backwards compatibility of any kind.
My PS2 has been long dead, and my game library for it fairly small, since I had given most of my games to friends who still had working consoles. I personally opted to go with the 40GB model. If PS2 gaming is important to you though, probably best to find a launch model, or pick up the 80GB before Sony does yet another hardware revision.
