Well, there is no Android for the TouchPad, yet. And there won't be, until the community creates one.
Google's not going to fund an Android for TouchPad project. They make more on a new tab sale than by providing an OS for a dead tab. Couple that with the fact that the user that can find and install a custom OS on their $99 tablet is not the same user that spends a lot of cash in the App Store. So, the best Android can do is convert some WebOS users. But anyone that bought a TouchPad at full price already passed at the option to own an Android tab, and anyone that bought during the firesale with the intention of switching to Android is probably already an Android user on some other device.
So, even if/when there is an Android for TouchPad, this won't grow Android's user base, developer base, or increase Google's revenue by any substantial amount. Throw in lost sales due to a $99 substitute, and I really don't see Android/Google gaining much, if anything.
