A) the not always online is wrong I think. It has to ping online services to say if you've got rights to a game and they stated over and over the importance of the cloud.. .in that "games ... are always with you where ever you are". I do think that its not "always online" but it does "require an internet connection" which is the bigger issue. (frankly I think it something PS4 will also have and the biggest reason EA backed off of Nintendo as they wouldn't incorporate that through Origin like MS and probably Sony have)
B) The 15 exclusives (8 new IPs) is not as big as you make it to be. Its for the entirety of the first year. So Q4 2013 all they way through Q4 2014.
For comparison, Wii U has quite a few known coming as well in its first year... (well not 8 new that we are aware of yet)...
1. Nintendoland
2. NSMBU
3. LegoCity
4. ZombiU
5. SMB
6. . Mario KartU (vs Sonic)
7. ZeldaWWHD
8. Wonderful 101
9. Pikmin3
10. Game & Wario
11. MH3U
12. Wonderful 101
13. ?NSLuigiU
14. Sonic Lost World
15. (very likely a few others I'm forgetting or will be shown at E3)
C) I was impress with the overall system and OS. It shows the next-gen focus is equally on services as games as I predicted early 2012. (though Wii U didn't follow through on that) However, they really should have followed Sony's lead and had a bigger presence to those games they intend to show at E3. Even one or two of the exclusives would have been significantly better than zero.
