Upgrade to RBR and Other Titles?

[pokeytrev]

I purchased Wellington's Peninsular War a few days ago, and caved and bought Republican Bayonets on the Rhine today. I noticed that RBR has smaller counters, doesn't use Manual Defensive Fire by default, and the graphics are noticeably different. I was just curious if there are plans in the works to bring some of the older titles up to WPW standards? It feels strange switching between the titles.
