Are there any Amazon-provided Windows AMIs that have the .NET 4 framework pre-installed? Unless I'm missing something, it looks like 3.5 is available on the images (such as ami-cab91da3), but not .NET Framework 4.
If not, can we expect updates to the AMIs to include .NET 4 in the near future? It's been officially released for almost two years at this point. Or am I responsible for installing it and building (and maintaining) a custom AMI?

The 'official ' Amazon EC2 AMIs for running Windows Server & SQL Server on Amazon EC2 (likely with Microsoft being involved in these offerings) primarily mirror respective official OS offerings from Microsoft (plus server versions eventually, like SQL Server or IIS). Therefore the .NET Framework 4 will only be pre-installed if either the provided OS (plus service pack) or the installed servers do require and respectively provide it as their default configuration.
That is the case with the recently Updated Microsoft SQL Server Offerings indeed, insofar SQL Server 2012 requires the .NET Framework 4 indeed, see Hardware and Software Requirements for Installing SQL Server 2012. Section Support for Microsoft SQL Server 2012 lists the respective AMI catalog entries accordingly:
