A bit worried Sony is shooting wildly
We have for active platforms
1. PS4
2. PS4
3. PSP
4. PSV (which will have unique touchscreen games)
5. PSVT
6. PS Move
7. PS Eye
8. PS VR (?) (unsure if this will end up happening)
9. PS Mobile
10. PS Gaikai (which can stream its own unique games)
Its almost like they want to take a shot at doing everything from Ouya to mobile games to console to handheld...
Some overlap, others dont, and im not sure how Sony intends to get network effects for each.
		
		
	 
Eh, going forward it's realistically more like:
Tier One
PS4 (with some games enhanced for VR)
PSV / PSVT
Tier Two
PS Move 
PS Eye
Tier 3
PS3
PS Mobile
This is the last calendar year of Sony's direct development for PS3. They even said all of their studios are on the PS4 bandwagon now. It gets its own slot this year, but not next year.
PSP is dead outside of Japan. No major Sony development focus on it at all.  
There will be no exclusive Vita TV software. Makes no sense at all.  
PS Eye only games and apps... I guess I can see it since it is more accurate than last gen's version and the DS4s have a lightbar - little more than dance games and the like though IMHO.
PS Mobile requires the slimmest of resources, but let's leave it separate. 
There will be no original Gaikai streamed games developed. It will be old games ported to the service, or a different format option for current games.
So The PS4 and Vita are the only platforms with heavy focus from Sony, then comes the Move/PSEye tier. The PS3 is on its last hurrah as it relates to serious development dollars from Sony, and the Mobile division is no resource monster at all.
