Here's what it could be...
Master System: I'd say this one is the most likely. Pricing games around $5-$6 would definitely induce me to buy some of the better titles for the system, especially if they release some of the better titles Stateside that only got EU/JP releases.
MSX: They said that this was coming sooner or later, so I'd put the chances at, "very likely." Still, it'd most likely be a Euro-centric release, with games priced at $6-$8 each.
Sega CD: If they're doing TG-CD games, then I don't see why not. I'd estimate a price point of $10.
Sega 32X: Due to hard drive issues, they might actually emulate the 32X before the Sega CD. And if Knuckles Chaotix is one of the first releases... *crosses fingers* Like SCD games, I'd say $10 each for games.
Saturn: Not likely because of hard drive issues. I'd put chances at, "slim to nil."
Atari Jaguar: I'd say that Jag emulation is more likely than 2600/5200/7800, if only because most games on the latter systems have better versions on the NES - and because most Jag games look more "modern." And that's only if Nintendo could negotiate rights to the games with whoever owns the licenses now. Look for a price point of $8-$9 if they come, which isn't very likely, but always a distant possibility.
Atari 7800: Less likely than the Jaguar, but more likely than the aged 2600. A price point of $5-$6 sounds about right.
Game Boy/Game Boy Color: $4/$5 respectively, I'd say. I doubt Nintendo will start to release these until they announce the DS's successor, but they WILL release them sooner or later.
So, if I had to guess anything, I'd say that the two are MSX and either the Master System or the Sega CD.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
