AndroidSpin actually confirmed on its site that myTouch 3G Slide will be getting the all new Android 2.2 Froyo when it's release next week.

Confirmed by HTC

if your phone was launched this year, we will most likely offer an upgrade for it to the Froyo version. This includes popular models like the Desire and Droid Incredible as well as hotly anticipated phones like the Evo 4G, MyTouch slide and upcoming models. We will announce a full list of phones and dates once we are closer to launching the upgrades. We are working closely with Google and our other partners to ensure we have the earliest access to everything we need to provide a complete and solid Sense experience on Froyo. We expect to release all updates in the second half of this year but can't be more specific yet.

The myTouch 3G Slide is T-Mobile USA's sixth Android smartphone, featuring a HVGA touchscreen display, full QWERTY keyboard, Swype, Wi-Fi, GPS, and a 5MP camera. The handset will be sold for $179.99 with a 2-yr contract agreement.
