Acer is set to finally throw its hat into the tablet ring, with rumours flying that the PC maker will unveil three new slates in New York later today. There’ll be 5-inch, 7-inch and 10-inch models, the latter packing Windows 7 while the other two will rock Android.

Suppliers in Taiwan have suggested Acer has pulled the release of its 7-inch tablet forward in order to lock horns with the iPad and Galaxy Tab before Christmas. It had been expected to come loaded with either Android 2.3 Gingerbread or the even more advanced Android 3.0 Honeycomb.

If that was the case, Acer would probably have had to have held off on releasing its Android slates until CES or even later into 2011. Now though, it’s looking likely we’ll get an official glimpse of their new wares early.

The 7-inch tablet was seen earlier this year being played with by Acer’s CEO on stage at a special event. Whether this device, replete with a QWERTY keyboard, is the same as the one we’ll see later remains to be seen.
