Interesting...I've seen an upgrade path for LR3 but no info on 4. If the upgrade to LR4 is $100 and the full LR4 is $300 and LR3 costs $135 (amazon, b+h) you still save $65 ($235 vs $300)..I haven't been able to find details on pricing, etc. I have been using the LR4 beta and I don't think I can go back to strictly photoshop elements.....
