Kobo e-reader PDF and PDB only

Shucks. The new Kobo eReader will not read anything except EPUB and PDF, which dampens my enthusiasm, considering how many MOBI and DOC file I've bought.  Their support folks answered my query with:
Hi John,

No, at the outset, only PDF and ePub will be supported. If we later make support available for other formats, you will be able to download an app upgrade.
