Looks like Palm pretty desperately want to get more Palm App developers that they are offering some pretty sweet deals to spice these developers to help them expand the App catalog.  Here's the message from Palm Developer Center:

• These are exciting times for Palm and our developer community. The Hot Apps promotion that we kicked off back in February is about to end with over 400 developers receiving a share of a million dollars. We recently launched the Summer Half Off promotion-a 50% discount for nearly every app in our U.S. catalog, funded by Palm. And we're just getting started.

• In July, we're launching the new PDK Hot Apps promotion-another million dollars to developers, this time focused on the C/C++ apps that were excluded from the original Hot Apps promotion.

• And we have one more program change that will benefit all developers. When we launched the developer program, we introduced a $50 per app fee to submit apps to our catalog. Effective immediately, we're waiving this fee and refunding to all developers any $50 fees collected in the past. If you're one such developer, you will see a credit in your PayPal account in the near future.

• Thank you for being part of the webOS community. We're excited to continue to evolve the Developer Program as together we build an incredible application catalog for customers.

Pretty sweet in my opinion, I sure hope they will be able both maintain and obtain more app developers.
