HP Tablet PC could launch as early as June this year

Engadget has reported that Hewlett Packard is working on plans to launch a webOS based Tablet PC early next year.
This is getting pretty interesting. The company has already hinted that they plan to offer Windows 7 based Tablets to their corporate customers.
HP is also said to be working on an Android based Tablet.
It seems very improbable that they would have three different generations of Tablets powered by three different mobile platforms.
HP is unlikely to drop webOS from their tablet plans. Android might be ditched in favor of it.
