I can almost ASSURE you that there'll be some sort of protection on ssbb. Look at it like this.. if they'd delay the game's launch simply because they wanted a perfect time for the launch, that'd get maximum sales (why they didn't launch it their normal time with Galaxy), then you know that such a big delay means the launch is important to them. I mean, it's expected to be game of the year, and hands-down game of the year for the Wii. Why have a potential game of the year have such an easy loophole for pirates?
On another note though, I really doubt that this last delay is for putting security on it, and it's not for adding other fun stuff in the game either. I only see 2 possible explanations for their latest delay (keep in mind that the US launch was moved a month back, while Japan's launch was moved back a week):
1) They're adding stuff to the US version that won't be on Japanese version (maybe they had technicals with licensing mumbojumbo w/ Japan).
2) They're dealing with translation issues, and with Nintendo being a Japanese company, they have a much easier time with a Japanese game, rather than translating it to US English.
I doubt (1) is feasible, as it's never happened before with ssb (besides trophies :/), that would anger a lot of Japanese kids, and they'd compensate for the lack of extras in some way. Also, I'm sure the game has been completed for SOME time now, and the only tweaks they may be doing is minuscule stuff like new stickers or trophies 'till launch. No fun new characters or stages. Hopefully new items
(2) sounds feasible, as it WOULD naturally take long w/ translating for US English. Besides, I doubt they're doing anything to Japanese version for the delay. They just.. figured having only one version get delayed would be RACIST, so they delayed them both.. with different time-frames :/
MY POINT IS.. that I strongly doubt this delay, and none of the previous delays as well, were intended to be there b/c they are adding security, or the release time for the Japanese version and US version would have the same delay time frame. This is not to say that they didn't work on the security a bit extra with the given time, but why would they gamble and work on security only b/c they have nothing else to improve on, with such a potentially big game?
...and I doubt anyone's going to be reading all of that xD
