I would definitely dump the old UCS R2's. If it really is the R2 in may, then I will be extremely disappointed. I was hoping it would be the Gunship in May and the AT-AT in the fall. No offense to the R2 Set but the new version will definitely de-value the previous one.
This is what pisses me off...The previous R2 set is like 7 to 8yrs old and the TIE Interceptor and Vaders is like 15 to 20 yrs old. And the later 2 look old and very outdated. My point is IF you are going to remake sets (I would prefer new ships), then why not remake the ones that need updating?
