I would like to see some fort of SQL (Express, Compact, etc) ported to support Windows RT. With Microsoft's push onto ARM, we would like to be able to build leading-edge Line Of Business apps that allow offline data storage and syncing. Normally we build applications like this with SQL Express or Compact and Merge Replication.--------------------Additional motivation / information:We have an application we would like to port to Windows RT, but it uses SQL Compact with Replication. The only thing standing in our way is that SQL Server isn't yet available in any form (Express, Compact, etc) on Windows RT / for ARM. The code is all written in WPF and .NET, so it would be a trivial port. And obviously we don't want to switch to a competitor's SQL technology, like SQL Lite (already available on Windows RT), nor rewrite our own replication & sync mechanism.We're a consulting shop, and in a given year about half of the apps we build require offline storage and sync'ing (so well over half of our entire company's revenue is from solutions built on SQL Merge Replication - either compact or express). So unfortunately the majority of our business makes it difficult to ever build apps for Windows RT without SQL Compact being ported to ARM.
