There are people who don't know the GBA and SP play the same games, so confusion is practically guranteed.
No manufacturer ever managed to have three top consoles in a row, usually they only get one or two tries at it. People say MS got a good start for a newcomer but they forget the Odyssey, the 2600, the NES and the PS1 were done by newcomers... think the Xenon can be likened to either the Genesis or the Dreamcast, depending how successful it ends up...
Even the analysts predict Sony won't be the leader next time 'round, they've alienated too many devs with their hardware and draconian practice (SCEA: "Hm, no. That game doesn't fit in with our desired image for the PS2. REJECTED!") and most of their support they're getting just because they're market leader. Many third parties already admitted to hating Sony and chances are they'll try to stop Sony from reaching the top spot again. If Sony were to rule a third time they'd feel too secure and withoput competitio, thereby falling back to monopolist practices. That would effectivelty hurt the gamer.
I wonder if MS learned from XBox 1 or if they'll release the Xenon at USD500 or something. Sony might fumble on that, too. Nintendo seems willing to keep their prices at kid-friendly levels (come on, I paid DEM300 for my SNES, that's maybe EUR150).
I hope they return to their "batteries included" approach of their monopolistic times. The gameboy came with a game (Tetris, the best killer-app ever), a link cable and batteries, my SNES had Super Mario World and a Super Gameboy included.The Cube? "Uh, sorry, you'll need a memory card and a game first".
