At this time of year, every press release must be taken with a grain of salt, but sometimes products announced on or around 4/1 can prove to be real even when they seem a bit unlikely (1GB of free email? Must be a hoax). It's in the vein of strange-but-true (I hope) that Unity Technologies announced a beta program for Unity 3D on the iPhone.
Unity's dynamic game development system (used by some fairly big names), if it makes the leap to the iPhone and iPod touch successfully, will give game creators a spectactular platform for rapid development. Hopefully that will include the unique interaction modes (multitouch, accelerometer & maybe even location awareness) that we saw at the SDK announcement. Can't wait!
