Here is the result from the GetViewHtml operation without the Type attribute set
<GetViewHtmlResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<GetViewHtmlResult>
<View Name="{1FBCBABD-6A12-48FD-836B-2E7DFD69388E}" Type="HTML" DisplayName="010103" Url="/REMOVED BY ME/Forms/0101031.aspx" Level="1" BaseViewID="1" ContentTypeID="0x" ImageUrl="/_layouts/images/dlicon.png">
<ViewFields>

</ViewFields>

<Where>
<Eq>
<FieldRef Name="RegID"/>

<ParameterBinding Name="NoAnnouncementsHowTo" Location="Resource(wss,noitemsinview_doclibrary_howto2)"/>
</ParameterBindings>
</View>
</GetViewHtmlResult>
</GetViewHtmlResponse>
After opening the view for Edit and clicking the OK button, the result becomes...<GetViewHtmlResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/">
<GetViewHtmlResult>
<View Name="{1FBCBABD-6A12-48FD-836B-2E7DFD69388E}" Type="HTML" DisplayName="010103" Url="/REMOVED BY ME/Forms/0101031.aspx" Level="1" BaseViewID="1" ContentTypeID="0x" ImageUrl="/_layouts/images/dlicon.png">

</ViewFields>

<Eq>

<ParameterBinding Name="NoAnnouncementsHowTo" Location="Resource(wss,noitemsinview_doclibrary_howto2)"/>

</View>
</GetViewHtmlResult>
</GetViewHtmlResponse>
Which is identical to the result of the GetViewHTML operation with the added Type attribute to the AddView operation.
