Toshiba’s first generation of Excite tablets has been much better received than the Thrive line, so instead of the company once again starting from scratch, the Excite family has been refreshed a couple of weeks ago with three new models – Excite Pure, Pro and Write.

But in its native land of Japan, Toshiba has made it a tradition in marketing tabs under the Regza moniker and the new trio is not set to be the exception from that rule. It’s therefore time to meet the Regza AT503 and AT703, the Japan-bound variants of the Excite Pure and Write.

For now, the Excite Pro doesn’t have a counterpart in the Land of the Rising Sun, but it’s not like you’re going to miss the thing, since it’s basically an Excite Write (or Regza AT703) sans the stylus support.

As for the AT503 and AT703, they look in every way identical to the Pure and Write, both in terms of their guts, but also as far as designs are concerned. What’s newsworthy is Toshiba has revealed a little more about the two slates, including their measurements.

The AT503, the cheaper model of the two, is quite surprisingly also thinner and lighter, measuring 10.3 mm in depth and weighing in at 600 grams. For comparison, the AT703 is 10.5 mm thick and weighs  671 grams, which to be frank sounds a little bulky for a 10-incher.

Chances are however the added bulk is caused by the packing of a more generous battery, since Toshiba claims the AT703 will be able to run for up to 9.5 hours (!) between charges.

Powered by an Nvidia Tegra 4 CPU, the Regza AT703 is about as high-end as things get in the Android universe, running 4.2 Jelly Bean, sporting a 2,560 x 1,600 pix res panel, plus things like 2 GB of RAM, 32 GB of storage, an 8 MP rear cam and Harman Kardon stereo speakers.

The AT503 is a lot more technically modest, though on the whole it’s still a decent mid-end slate. It packs a Tegra 3 processor, plus 1 gig of RAM, 32 GB of internal memory, as well as a 1,280 x 800 display.

The bad news in this entire equation comes from the pricing front, with the AT503 set to see daylight for 49,800 JPY ($525), while the AT703 will go for a whopping 89,800 JPY ($948) starting June 21. Fortunately, that pricing structure won’t stick in the West, where the two are to cost $300 and $600 respectively.
