Still no official release date set as of yet, but we hope to announce some information soon, so please stay tuned. Personally, I share your irritation though... why can't the developers just release the damn game already...
Regarding beta-testers, we don't have any need for additional testers atm, but I'll definitely post if/when the situation changes. PocketPCs with a MediaQ gpu, as most people already know, suffer from performance penalties compared to other devices but you should be able to adjust rendering quality in order to acheive a playable framerate.
(and lastly, i'd just like to take a moment to recognise the attention-to-detail in sponge's last post, for actually looking up the ascii character code for the ¹ in T¹
