If you want a Office2013 to be created for a future version you can suggest new Product Ideas for future versions (or vote for existing ones) at http://ideas.infragistics.com.

Steps to create your idea:

1. Log into the Infragistics Product Ideas site at http://ideas.infragistics.com (creating a new login if needed).
2. Navigate to the product / platform channel of your choice (e.g. WPF, Windows Forms, ASP.NET, HTML5 / Ignite UI, iOS / NucliOS, etc.)
3. Add your product idea and be sure to be specific and provide as much detail as possible. Explain the context in which a feature would be used, why it is needed, why it can’t be accomplished today, and who would benefit from it. You can even add screenshots to build a stronger case. Remember that for your suggestion to be successful, you need other members of the community to vote for it. Be convincing!

The benefits of submitting the product idea yourself include:

-          Direct communication with our product management team regarding your product idea.

-          Notifications whenever new information regarding your idea becomes available.

Additional benefits of the Product Idea system include:

-          Ability to vote on your favorite product ideas to let us know which ones are the most important to you.  You will have ten votes for this and can change which ideas you are voting for at any time.

-          Allow you to shape the future of our products by requesting new controls and products altogether.

-          You and other developers can discuss existing product ideas with members of our Product Management team.

The product ideas site allows you to track the progress of your ideas at any time, see how many votes it got, read comments from other developers in the community, and see if someone from the product team has additional questions for you.

Thank you for contacting Infragistics.

Hello Marcus,

 Thank you for your post. I have been looking into it. Currently we do not have Office2013 Theme. I have created a sample application and changed the default styles of the XamRibbon to look like the pictures you have attached.

I have used Snoop tool(http://snoopwpf.codeplex.com/) to find which components have to be changed and used the default styles of the XamRibbon.

The Default Styles you can find on the following directory: C:\Program Files\Infragistics\NetAdvantage 2013.1\WPF\DefaultStyles\Ribbon.

Please find the attached sample application and feel free to let me know if you have any further questions on this matter.
