Motorola Droid 2

I currently own a droid eris, tired of it. wanted an incredible, i feel like its about to get cut off since you hardly hear any buzz about it. its starting to seem old and outdated. This new droid 2 is like the Incridble in a new shell. except from the camera. which i was hoping for at least 8 megapixels. but this fone has all the things i want on my eris lol. But is it really worth the upgrade. am i going to be left high and dry after 6months (refference to eris being dropped in 6 months) will I ever recive an update past 2.2? What will i be getting into when and if i buy this phone.
