If you have watched Silverlight's Future Keynote,you will agree with me in this situation.
When I first heard Silverlight will have "GPU Support", I've said : "OK.Now that was a killer move against XNA."
That shows us XNA has a shadowy-future.There are also rumors Silverlight will be supported in XBOX 360 and if that happens its going to prove us that XNA will die in the next releases of Silverlight.Because XNA wont be needed anymore as long as Silverlight does its job.
I think there's another Keynote needed about XNA's FUTURE.
Waiting for your thoughts,
What do you think about this?
