According to Touch Arcade:
The sad part is that the Retina-ready graphics in this new Tetris look great on the new iPad, and the addition of the "one touch" control method make the game a lot more fun to play. But, again, much like the iPhone version, it makes absolutely no sense why this couldn't have been an update to the existing game that everyone already paid anywhere between 99¢ and $7.99 for.
It's really hard to get behind EA as a developer or publisher on the App Store when they're more than willing to pull these kind of hijinks. It's one thing to submit new users to a bevy of IAP options, but by pulling the old game from the store entirely, if you lose the original Tetris .ipa file for any number of reasons, getting the game again is going to set you back the full purchase price.
Here is the new link for Tetris For iPad, it costs $6.99 with many in-app purchases for the avid fan.
Pulling a stunt like this just gives me one more reason to install Cydia on my iPad. Smooth move EA...
