I don't read the news threads, so forgive me if this too has been posted. Rumor is swirling that the 370t or a slight downgrade of it will be the rumored Nexus Tablet priced at $199.

The second update is that sources in India expect the 370t to be available there in May. The previous was window was broader: Q2. While this isn't US specific, I do think it still helps narrow the window.
