It’s the release day of Sonic the Hedgehog 4: Episode 2, and to remind everyone of that SEGA has released a launch trailer for the game. The trailer shows just about everything not shown yet in other officially released media except for the final zone, so those wary of spoilers may want to avoid it:

The most interesting thing about the trailer is that it says “To be concluded…” near the end, hinting at what may be a third episode in the Sonic 4 saga®.

It also shows the release dates for most of the platforms the second episode releases on. It’s already been released on Steam and it will be released later today on Playstation Network. Xbox Live Arcade and Nvidia Tegra 3-powered devices will get the game tomorrow and iOS devices will get it the day after. It seems like the game won’t be available on Android devices without Nvidia Tegra until June. Windows Phone users will be able to buy it in July.
