Just in case you haven’t guessed already, the analysts over at Goldman Sachs are speculating the next-generation iPad will appear next year, in the second quarter, to be exact.

They anticipate the new Apple (AAPL) tablet will host a 9.7-inch display and will be thinner and lighter than before. We’re also going to see a built-in camera and a mini USB connection – perhaps in anticipation of upcoming European standardization on the interface.

The new tablet will once again be manufactured by Hon Hai Precision Industry, the analysts say. (And while they don’t say it at least some of us here at 9to5Mac anticipate it will be powered by a new and faster A4 — A8? — Audi/processor).

Goldman’s predictions are in line with reports last week which claimed Apple is already lining-up potential component suppliers for iPad 2.0.

Apple is understood not to have made a final decision as to whether it will make a smaller 7-inch version of the iPad, and the company declined to comment on this.

Apple sold over 3 million iPads in the first 80 days following the product’s April release. Production has reportedly now ramped-up to three million units per month.

Meanwhile almost every Apple competitor appears to have plans to introduce tablet devices next year as the market heats up.
