wPDF Plus in Delphi XE3

I've been working on upgrading our components to Delphi XE3, but I've hit some problems with wPDF.

I'm using version 3.75, but as far as I can tell it doesn't support XE3 yet.

I've managed to get the standard version working by adding the correct defines to the inc file, but when I remove the INTWPSWITCH define to enable the Plus version, Delphi won't compile the WPT2PDFDLL.pas unit.

Is there any way I can get the Plus version to work with XE3, or will I just have to wait until a new version is available? And if so, is there a timeframe on when XE3 support will be available.

Thanks, I'll be looking forward to that :)
