IceFrog Blog - New Loadscreen:
There is a new loadscreen in the works right now. It will most likely be included in the next update.It's nice that IceFrog is adding a new loadscreen for DotA, Let's see if Kunkka (DotA Loadscreen Artist) reveals any artwork of the upcoming surprise. You can send your feedback to IceFrog for the suggestions.
6.69 development has also been progressing nicely. I'm not sure exactly when it will be finished just yet, but I'm aiming for something in the near future. I will post another update when it is closer.
If there's anything you'd like to see in the new loadscreen, or any suggestions for 6.69 or DotA 6.70 in general, please let me know. It is always helpful when you guys email me your requests so that I can make sure the updates meet your expectations.
