The non-backwards compatibility thing I saw coming and it was why I stopped buying stuff through XBLA and PSN a little while back. I'm holding out on getting any next gen consoles for as long as I can, I'm sticking with the PC, D had it right all along :p. I'm sure ill eventually get one, when enough exclusives I'm interested in builds up and there's an eventual PS4 redesign. The last half of this generation I've built up such a huge backlog of games it's insane so ill have plenty to keep me occupied.
Of course I had it right all along.
I been doing PC gaming since 1995 and I knew then and there, this was it for me - this was the place to be. While sometimes it can be a pain-in-the-ass to get some old games going, you can still find ways to try to get them working. Often, it just takes running a game in Compatability Mode for an Older OS it actually worked on; Disabling Desktop Composition; Disabling Visual Themes; and Running as an Admin. If that ain't enough - see if a game has any Source Ports, Mods, Emulator Programs (like DOSBox), and anything else to make it run on modern PC's.
Hell, I bought Shadow Warrior: Complete yesterday ($2.39 on GOG currently) and got it running on a Source Port;
and my retail copies of Thief 1 + Thief 2 + System Shock 2 run fine on my modern Win 7 64-bit OS (after installing their most recent "Unofficial" patches).
I think the PS2 did so well b/c it was backward compatible w/ PS1, as well - it made people say, "I love my PSX and can play most of these games on PS2; PS2 has some cool exclusives; and it has a DVD player - this is a no brainer." PS3 and 4 lacking this backward-compatibility stuff - not good for a launch. On PC - like I said, it sometimes can take just a little bit of tweaking and/or modding to run old-ass PC games here.
I know. But never say never. 
Anyone else find it interesting how Sony is giving examples of the PC as a benchmark when talking up the PS3?
That's a definite change from last generation. PCs seem to be getting more respect. I wonder why that is. Maybe it is a sign that the consoles this generation don't want to go overboard.
I think PC is also getting much respect b/c PC's aren't super-duper expensive anymore to build (especially if you buy parts during sales);
PC gaming prices and sales fluctuate within no time like crazy (especially on the digital space - where there's so much competition b/t Steam, Amazon, GameFly, Gamersgate, etc);
and that consoles (PS3 and X360) have gotten so old now that the PC is leaps and bounds beyond what they're doing (at least, for now).
Also - it doesn't really look like the PS4 or X720 really look like they have a big enough library and/or that exclusive killer-app...yet.
Maybe we'll see something exclusive that's worth a damn on E3?
While Watch Dogs PS4 demo looked great....yeah, that was running on a PC (that's a slap in the face for console gamers) and is being multi-platformed EVERYWHERE.
I also think that's a major problem for consoles, too - it seems like many of their exclusives are timed-exclusives that will eventually hit the PC, unless it's a Sony-published or Microsoft-published game. And even in some instances, these might wind-up still on the PC, a bit later.
